Theres nothing cozier than a down comforter, which is why many of us pull our duvets out of storage each autumn to prepare for the cold months ahead. By the end of the winter season, however, your favorite piece of bedding may begin to feel not so fresh. When the time comes, many will take their beloved blanket to the dry cleaners and rack up a hefty bill, which often leaves them wondering if its possible to just toss it in the washing machine. The answer is yes, but it must be done correctly or you could damage your comforter.
First, load your down comforter into an extra-large front-loading washer. If you dont have one at home, you can find one at your local laundromat. Try to spread the comforter out a bit, and avoid twisting or folding it excessively inside the machine. The more space the comforter has to move around, the better the end result will be. Add a mild detergent, sparingly. Use less than the recommended amount, and whatever you do, do not add bleach.
Set the washer to the gentlest cycle possible. If theres a delicate setting, thats what you want. Ideally, the wash will be set to warm with an extra or extended cold rinse cycle. The most critical detail here is to make sure theres no detergent residue left after the rinse.
Place the comforter in the largest capacity dryer available with the dryer balls or tennis balls. The balls will move around and agitate the comforter, preventing the down from clumping while it dries. Set the machine to 30 minutes on the lowest setting.
Every half hour, remove the comforter and give it a little shake to help fluff it and distribute the down. Make sure that it doesnt feel too hot. Continue doing this until the comforter is completely dry. When the entire thing feels fluffy, light and lofty, youll know its done. If for any reason you cant wait until youre certain that the comforter is fully dry, you can hang it up in a sunny, warm spot either inside or outside your home until its ready.
Always keep your down comforter inside a cover when youre using it. Under normal circumstances, you should only have to wash the cover every few months, and the comforter itself every other year or so. A high-quality down comforter should last many years, and with proper care, can keep your nights warm and cozy for the long haul.
If youre looking to pick up one of the different machines available through Gold Watch Project, youll first want to have some information regarding the use and specifications of our machines. These are technical machines with professional, precise requirements and standardstheyre not for just any old hobbyist doing a weekend dig. In order to prepare you and to help you understand the use and functions for our various devices before you purchase one, weve gathered up plenty of gold washing machine information on this page.
Currently, Gold Watch Project offers five different pre-set sizes of gold mining machines: the M30, M50, M100, M200, and M300. These machines are numbered by their weight capacity in tonnage, meaning that you should consider the scale of your operation before purchasing a machine. After all, theres no need to get a 200-ton capacity gold mining machine if youre only going to be doing a 50-ton job.
Each of these machines also has different requirements for things such as water usage, fuel consumption, and more. With regards to water usage, our various machines require anywhere from 500 gpm to 3200 gpm. Keep this in mind when making your purchase, as a machine for which you cant reliably provide enough water will be unhelpful. The same goes for their fuel usage, which can range from two liters per hour on the low end to four liters per hour on the higher end. Keep both aspects in mind when making your purchase to make the most of your gold washing machine.
Other aspects of our machines are designed to make them any miners best friend. Unlike machines from other manufacturers, our gold wash plants do not require you to hook them up to separate generatorstheyre self-powering. They also work with most existing pumps, though not with every varietycheck with us to see if your pump is compatible. Theyre also environmentally conscious, not requiring mercury solutions like other machines do. Our machines are also very easily repaired, and the repairs dont require expensive custom-made parts.

Welcome to GWP, where we make high-quality, affordable gold wash plants for sale. Our product lineup is designed to efficiently handle anywhere from 30 to 300 tons of material per hour. Each wash plant has three proportionately sized sluice boxes designed to optimize gold recovery in all conditions.
Each machine is a complete portable plant; there is no need for additional screens or sluice boxes! At the top is an extreme duty grizzly bar section that will take up to 24-inch rocks (91 cm). Classification begins when the material is placed on the grizzly bars, and high-pressure water separates the sub-1 (25.4 mm) material from the large rocks. Next, the screen deck further classifies the material, and sub-.25 (6.35 mm) material drops into the sluice boxes, remaining sub-1 material passes through the nugget trap into the final riffle set for capture, and larger rocks get discarded.The sluicing system has three boxes that are independently adjustable, and with anywhere from 20 feet of sluice box on our 50-ton units to 40 feet of wider boxes on the 200-ton units, gold recovery is excellent. It often exceeds 95%, even with fine gold down to 200 mesh! Whats the key to such remarkable recovery? Science. This portable gold mining equipment was based on the performance data found in a landmark technical report on sluice boxes and riffle systems. Watch the video of our M50 wash plant.
Our wash plants for sale are always mercury-free, and they require no additional recovery equipment. Setting up your wash plant is fast and easy--it usually takes less than 2 hours. When you need to move the mining site, you can drag the excavator and enjoy the ease of a highly portable wash plant.
Our machines range from 30 to 300 tons per hour while maintaining a long life and less downtime. Reliability is essential to save time and increase profits. We ship worldwide so that you can pay less money and recover more gold than other machines.

A SR101 reader asked me a question about washing machine stains, the kind where you don't have a stain on your clothes before you wash something, but then you take it out of the machine and a stain has now appeared. SR101 Reader asks:I often have stains on my clothes that weren't there before I put them in the washer. Could this be from fabric softener?Taylor says:Thanks for your question. I just hate stains from the washing machine itself, since it means more work for you when all you want to do is get your laundry done.You've actually identified one of the biggest culprits which causes stains to appear on your clothes after they get into the wash -- fabric softener. That is because most softeners are oil based, and if too much is used, or added too soon or late into the cycle, or hits your clothes without being diluted enough, it will cause oily spots on your clothes. Typically, these spots are about the size of a dime and look almost milky or bluish, almost with an oily sheen to them.You can learn more about fabric softener stains here, and how to remove them.However, you've not shared with me what your particular stain looks like, and that is important in being able to identify what it is. There are many types of colored stains which can appear on clothing and other laundry after it has been washed, including:Oily stains, with a bluish sheen - often fabric softener stains (as mentioned above)Brown spots, that appear a bit oily - sometimes caused by an oil leak from your washerBrown spots or marks, or sometimes orangish - perhaps rust stainsOily spots - perhaps from HE laundry detergentBleach stains - sometimes from bleach, sometimes from other causes such as laundry stain removersInk looking stains or streaks - these can show up even when no pen or ink presentBlack marks and stains - can be caused by oil, or something elseFading chalky like stains, especially on dark garmentsDifferent colored stains that may actually be dye transfersVariety of other colored spots and marks, including pink, purplish, blue, and moreNotice I didn't add a cause or cure for all of these types of spots, because sometimes the issue is unknown, but it's common enough that multiple people have reported it.This page is ever evolving, as more people send in photos, stories about what problems they've experienced, and solutions they've come up with. So make sure to read down to the bottom for all the ideas and problems experienced, and to see if what is happening to you has already happened to someone else. (The comments are quite populated with additional stories, as well.)I don't always have an answer, but I know if we all add our bits of collective wisdom we'll get to the bottom of all of these issues eventually!Make Sure Your Washer Is CleanThere are so many possible causes for washing machine stains that it is often difficult to narrow down what the cause of them is.To help with this issue, first make sure you thoroughly clean your washing machine, because a dirty machine can itself be causing the spots and stains, and it is often the easiest remedy!Check out my article on how to clean your washing machine here.Make Sure To Identify If Your Stains Are From Your Washer Or Your DryerFurther, along with cleaning your washing machine, before you can identify what is causing your mystery stains, you've got to ascertain if the stains are actually coming from your washer, or from your dryer.If the clothes aren't stained before washing, but they come out of the dryer stained, you don't actually know, unless you examine the clothes carefully again after washing, but before the dryer, which of the two machines is causing the trouble.Here's my article on mystery dryer stains because that might actually be the problem you're suffering from!Read on below for more pictures from readers, and possible ideas for what is causing your stain, and how to fix the problem.
B wrote me in this laundry question, along with sending in these pictures of the problem she is having.B says:Lately, I've been getting brown mystery stains from my washing machine. I know it's the washing machine because I've checked before putting the clothes in the dryer. On the lighter fabrics, it almost looks like it's been burned or smeared with mud and sometimes has the imprint of the surface of the washing machine (a bunch of little holes). I tried cleaning the inside of the washing machine, even sticking rolled up paper towels into the little holes, but there was no residue. I tried just rinsing the stains to see if anything happened, but since I have no idea what's staining my clothes, I don't know how to fix it.It doesn't seem to happen with every load. I'd been adding vinegar to my loads to help remove stains and when I saw these new stains, I stopped, but they're still showing up. Help!I have so much laundry to do and I can't afford to ruin my favorite clothes or my husband's work clothes.Taylor says:B, I am sorry you are having trouble with stains from your washing machine.It is very frustrating to put clothes in there, to get them clean, just for them to get stained during the washing process.I cannot be sure of the problem, but it sounds like it is rust stains, especially based on your description of the imprint of the washing machine drum being involved.Unfortunately, if a part of your machine begins to rust, some of the rust comes loose during the wash cycle, at least some of the time, and then can deposit on your clothes during the cycle. This is most likely to happen if you let your clothes sit in there for a while after the machine finishes, but can also happen during the washing process itself.One way to check to see if these are rust stains is to try to remove them while they are fresh, and before you put the clothes in the dryer. Something mildly acidic, like lemon juice or vinegar, when dribbled onto the fresh stain, will typically lighten or remove it. You can also use a commercial rust stain remover to remove these stains, as long as what you choose is safe for clothing (and for the color clothing you have the stain on).Typically, when you are getting stains from an appliance, such as your washing machine, it makes sense to clean it. However, when you clean your washing machine you may use chlorine bleach. In this instance, that would be a bad idea since chlorine bleach can cause rust stains to set.Instead, you can try to clean your rusty machine with a rust stain remover designed for appliances. (Click here to read rust stain removers reviews provided by other readers of this site.) The one that first comes to my mind is Super Iron Out, although many products are available that could do the job.If that does not remove the rust from your machine, and you continue to see these stains continuing, it is time to call a repair person. You may be able to identify and replace the rusting part. Unfortunately, if the problem is severe or the machine is very old it may cost more to repair than replace it.Of course, I am not for certain it is rust, although this is really the most common reason for these mystery stains. If it isn't rust though, I really don't know what it is, unless it is grease from your machine. If it were this, however, I would expect a slightly different color than what you describe, but if it doesn't respond to the lemon juice, but instead is removed or lightened with dishwashing liquid, this may be the culprit.I know this may not be what you wanted to hear B, but I do hope it helps you identify and solve your problem. I know how frustrating it can be to get behind on your laundry because of issues like this.Does any other reader have any other suggestions for B about this problem, or how to fix it? In addition, have you suffered from similar stains in your washing machine? If so, did you identify what caused them, and how did you fix the problem? Please tell me in the comments.In addition, you can also ask your laundry questions here, as B did, and I will give it a go to answer them.Possibly Washer Transmission Is Leaking Oil***Update: A reader wrote in suggestion this as the culprit:Your washer transmission is leaking oil into the drum. Replace the spindle seal or better yet buy a new washer.Another reader suggested that it was some type of gunk build up. She stated:The brown mystery stain looks like what we get from our lovely-horrid- front loader. It's gunk that collects inside the washer because it does not dry completely. I clean my washer once a week because of this and still have the gunk build up. It's very difficult to remove from your clothes as well. Any help would be appreciated.***End UpdateHere's a photo of what the stains look like from a washer that is leaking this oil, sent in by a reader.The reader stated, "Must have transmission oil leak in washer - entire load of white clothes have little brown spots. Found something on washer wall that appears to be gooey oil. Will anything remove this from the clothes?"
Isa says:Please can someone help, I just went to grab my washing out of the machine to dryer and spotted two of my husbands rusty screw bits (sigh) from the previous wash!"Luckily" they seemed to have got tangled up in the towels and the clothes are undamaged, however I know it's hard to get rid of any stains once something has been washed once, especially rust :(Does anyone have any tips? Also need to clean the rust from the rubber seal as you can see...Susan says:I haven't checked to see if I have solved my problem yet, but in trying to figure it out and looking inside my washer, I decided to wipe with a towel inside the rubber gasket at the opening of my front loader. It turned out it was full of brown gunk! We have a well and although we have a rust filter, it may be that. Meanwhile, I cleaned inside that rubber gasket very thoroughly. Taylor's ResponseIsa and Susan, along with cleaning around the rubber seal, which you've both identified, rust can be a problem for washing machines, especially those that use hard water, or well water.If you feel like you've got rust in your machine, I suggest using an appliance cleaner that is made for rust, such as Iron Out.You can read more reviews and uses for Iron Out here. It is a very powerful product that can help with this exact problem.Here's a caution for you though: If you use the Iron Out, be sure to get it well rinsed before you put colored clothes in it, as it will leave bleach spots if you don't.
I recently washed my daughters clothes, and when I went to bring them out of the wash, I notice large black stains all over some of her white and pink shirts. They look like a pen had burst inside the washer. This has happened a few times before, and I am never able to get the stain out. I am so confused and upset at the same time. I figured it may be that my washer need cleaning, but these stain/smudges are terrible. Please help!
I have been having a laundry issue for the past several years that I simply cannot figure out. I have many orange cotton T shirts without any stains that come out of the wash stained on a periodic basis. I wash them with like colored clothing (all of which have been washed MANY times before) in cold water using only powdered detergent and no fabric softener.These orange T shirts, and only the orange T Shirts, get dark spots and splotches in many places on the shirt. No other clothes show any of these stains other than my orange colored T Shirts. When I get the stains, I spray them with advanced formula Shout, let them sit a couple days and rewash. Upon rewashing, the stains always come out. However, I have no idea where and how these stains appear from the washing process, but I am very frustrated. I have attached a picture of a shirt I took out of the laundry today. Any thoughts? Any assistance would be most appreciated.
QuestionThe photo above was sent in by a reader, anonymously, and she asked, "What are these black stains that appear on my baby's clothes, and how do I get rid of them?" AnswerIt's hard to tell from the photo, but sometimes when you wash clothes in your washing machine, and then they come out stained, it is not caused by the machine at all, but instead by something about the clothes themselves.I'm not completely sure, without being able to examine the onesie you've sent in, but it looks like perhaps you've experienced a dye transfer stain, based on the look of the smudges that is mainly around the words which appear to potentially be thread embroidery.Dye transfer stains can happen when the dye, such as on the thread, isn't yet colorfast, and when it gets wet and washed, bleeds and redeposits on surrounding cloth, in this case a white shirt which is why it shows up so visibly.You can read more about dye transfer stains here, including possible ways to remove these stains.In addition, you can sometimes prevent stains like this from happening by using a dye catcher cloth in your laundry load. You can read more about these color catcher cloths here.
Marieta originally sent in the before photo, asking how to remove the stains to these shirts that were caused by her washing machine. Marieta asked: "Help!!! I have no idea what got on these in the wash! I've rewashed on stain fighter cycle with all the following added to cycle: bleach, Dreft spot remover, Shout in wash, Oxiclean in wash and this didn't work. Suggestions please!"Then, before I even had a chance to suggest anything she got it off all by herself, and sent in the after photo as well.She actually used a variation on what I consider to be the best homemade stain remover, which is hydrogen peroxide and dish soap. (You can read more about this DIY stain remover recipe here.) She explained that she made a paste of peroxide, baking soda and blue Dawn, soaked the shirt in hot water in the sink for 10-20 minutes and then washed it two times. Both times, as she washed, she added Clorox bleach crystals.(I would note that I would be careful about adding the bleach to any wash with colored t-shirts like this, unless the stain is so bad you don't care if you get bleach stains, because it's ruined otherwise. The stain looks greasy, which is probably why the peroxide and soap combination worked so well, so that would be my first suggestion of what to try!)
Katie sent in the photo above, but several readers have experienced several problems.Katie says:Has anyone ever dealt with these mysterious faded spots? They have just started to appear and are ruining my clothes!It isn't every load, I can't find a rhythm or reason. I have an old school washer and dryer and I haven't changed detergents.Anita Hacker says:I stopped using softeners and still continue to see oil like stains especially on black or dark colored tee shirts. I have one very old donna Karen tee shirt that has been washed 100 times and never has had a stain. I believe it is in the fabric dye and this is the fault of the manufacturers. They should test this by washing their shirts before putting them on the market. Of course this is not to their advantage. I don't think I have ever owned a black tee shirt that survived one wash without a stain appearing. Dry cleaning would solve the problem but that is very expensive. Someone should really investigate this problem as it is costing the consumer a lot of grief and money.Phyllis says:The same thing was happening to me. I discovered, use COLD water all through. Fill with cold water and soap before adding the dark tees. Then only let cold water in. I found it was the way my HOT water came into the washer that was causing these light spots. Hope this helps. I also have many dark towels with lighter spots, or reddish areas.
Taylor's note: I got this detailed explanation of what Ag925 thinks is causing many of these stains and spots on clothing. I am not personally saying this is correct, but I would love to hear from others with your thoughts on this possibility of what may be happening in your machine to cause this problem.Ag925 says:I have seen these spots on anything made of cotton (not just t-shirts) but have found they are most obvious on my cotton t-shirts. After some experimenting with my wash and doing some research, I have learned that detergents for high efficiency (HE) washing machines contain a silicone oil called dimethyl polysiloxane that is used to make the detergent less sudsy. The spots occur when the detergent comes in direct contact with your cotton clothes before it has completely dissolved in the wash water in the washing machine. Cotton loves to soak up this silicone oil...What will help: If you have an older washing machine that is not high efficiency, use a laundry soap that is not made for HE machines (I found cold water versions are best). OR you can use as little HE soap as possible and add it to the washing machine first along with a few inches of the warmest water for what you are washing before you add the clothes. If all else fails, repeat the wash cycle with no detergent added before drying the clothes.If you have an HE machine, you don't have control over when the detergent is added: use as little detergent as possible with the warmest water possible. If the spots are still occurring, try changing detergents or check your washing machines instructions for using detergent not made for an HE machine (most do). You can also repeat the wash cycle without any detergent.Taylor says:Thanks for this explanation! Like I said in my introduction, I have no idea if this is the cause of spots for everyone (most likely not, since many things can cause such mystery stains) but I would love to hear from others about this possibility, sharing if these suggestions helped any of you. I sure hope so!
Cathy says:Lately some of my darker colored laundry has been coming out after being washed with what looks like bleach stained spots. I do not use bleach in my colored laundry. My washing machine does not have an agitator and has a sensor for the water level. Also I do use the Downy ball for fabric softener. I would really appreciate some help figuring this out.Taylor says:Thanks for your question Cathy. It's a common misconception that bleach stains come only from using chlorine bleach.Although that is a very common culprit these can happen even from non-chlorine and color safe bleaches, or detergents or laundry stain removers that contain such products.However, it takes a lot for color safe products to cause bleach marks. Typically in those instances it is caused by improper application of the product, most often adding the product in an improper way such as full strength directly onto the fabric.That's not always the case, but it often is. Here's my article on the proper way to add liquid laundry detergent to the wash.Further, here's my article on color safe and oxygen bleaches in case this may be your culprit.Further, many laundry pretreaters, if left on too long before washing, can cause these same spots.Finally, don't forget about the issue of acne products causing this problem. The benzoyl peroxide in these products is often the cause of such mystery bleach stains if the items stained have been worn or used in the bathroom when applying these products.
Mary Ellen says:It only happens with the oranges and reds, and happens even if I wash them by themselves. I was wondering if it could be caused by hard water? I don't have rust in the drums and I don't use fabric softener. The stains are dark, like a dark slate gray or blue.SR101 Reader 1 says:Sometimes I get gray streaks or a stain on linens after washing. What causes that and how do I remove it?SR101 Reader 2 says:I buy red towels in Wal-Mart to use as guest towels. I wash them prior to use in warm wash/cool rinse cycle using a liquid detergent that I add to water prior to putting in towels.After drying I have noticed on some of the towels blue stains the size of a quarter in random areas of the towel.I don't use liquid fabric softener, just white dryer sheets.
SR101 Reader 1 says:Hello. Can you help me please? On 2 separate occasions, months apart, 2 of my t shirts have came out of the washing machine with pinkish stains on them. The first was just a few small spots, but the 2nd one has one larger stain on it and I'm baffled to how or why this has happened.SR101 Reader 2 says: I have a new washer/dryer machines. This has suddenly started leaving pink spots and stains on my white clothes. No coloured items are going in the wash and the machine has been checked by a repair company to see if any red or pink items are stuck in the drum and nothing has been found. I am using washing powder and fabric conditioner but neither are pink in colour. Any ideas?
We have a Whirlpool Duet front load washer, periodically my wife has clothes that come out with purplish tie dye looking stains in her clothes. We use Tide Free HE detergent and she claims that she adds the correct amount. It's usually only one item of clothing that comes out stained. Any ideas???
Here's a question from a reader that has me baffled, but I'm adding it in hopes that someone else may have some insight into it.SR101 Reader's Question:We have a Whirlpool Duet.My mother-in-law lives with us. Fairly often when she has washed a load of her whites only, her clothes will have a beige colored stain often at a seam or the neckline or waist band. These seem to be impossible to remove.It only occurs with her clothing, not ours.We use the same detergent and fabric softener.We've cleaned the machine thoroughly but they still occur.Could it be her makeup being dissolved in the wash water and staining her clothes? Again, it never occurs on our whites. My mother in law is elderly and does use make up foundations etc.It's driving her crazy and as a result, me too. Thanks.Taylor says:Hmmm, this laundry and stain removal question has me stumped! It is now driving me crazy too, because it is only happening with your mother in law's clothing, not yours too, which suggests it is something to do just with your mother in law, and not the machine itself.I am wondering, based on the location of the stains as areas where we perspire a lot, if it has something to do with that, and a reaction between the heat and/or other detergents and some medication she may be taking? I have heard about medications changing the ingredients excreted in a person's sweat, which may effect the ability to remove the stain.Here's my suggestions for removing sweat stains, but this would most likely not be helpful for something related to her medication. Of course, that is a completely wild guess, so I'd love to hear from even more readers who may have an idea about this unknown stain from the washing machine!

Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant. The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate. When the mined gravel is fed into the washplant. It is classified by particle size using various stationary or vibrating screens. Classifying gravels provides for more efficient gold recovery, reduced water consumption, and facilitation of mine site rehabilitation, and is practiced by most operators. The oversize material, usually larger than two inches, slides out of the washplant into a pile where it can be moved by a front-end loader or bulldozer. The undersize material and gold-bearing gravel is mixed with water and flows through the sluicebox where the gold and heavy black sands are concentrated. Tailings are gravel, sand, and other materials accumulated at the end of the sluicebox. Tailings are routinely moved away from the sluicebox by a loader or bulldozer.
The water that carries the gold-bearing gravel through the sluicebox becomes sediment-laden and turbid. This muddy process water flows from the end of the sluicebox over a pile of fresh tailings into a series of settling ponds. These ponds are designed to hold the muddy water long enough for the fine sediments to settle. The physical design of the ponds depends upon the amount of water flowing through the system, the sediment characteristics of the gravels being worked, and the physical characteristics of the site. Most mines use a series of small settling ponds to permit more flexible water management. Small ponds are usually easier to build, repair, dean, replace, bypass, and rehabilitate than larger ponds. The use of pre-settling ponds is encouraged. A pre-settling pond is located in the tail race between the sluice and the first settling pond. Sands and other heavy settleable solids are collected here where they are easy to wash.
However, some zero-discharge systems do have occasional discharges, usually due to water seepage through pond dikes. This seepage almost always meets the settleable solids effluent standards, and in most cases, Is probably of better quality than the water discharged from typically operated settling ponds. I.e., less settleable solids and lower turbidity. Carefully designed and Implemented water management practices are required to achieve zero discharge of muddy water into adjacent streams. Water used in the sluicing process Is pumped from the nearby stream through the washplant and into the settling ponds. Water Intake from the stream Is suspended when the ponds contain adequate water to support continued sluicing operations by recycling pond water to the washplant. In some cases, groundwater seepage Into the settling ponds may be sufficient to eliminate the need for adding stream water to the system. The practice of zero discharge and the recycling of mine water contributes to compliance with federal effluent limitations and State water quality standards.
Placer mining involves equipment ranging from a simple gold pan all the way up to trucks, excavators, and a gold wash plant.This type of gold prospecting usually involves less investment and will consistently yield small amounts of gold, with occasional bonanzas for those who are persistent. If you can learn to reliably return from every trip with decent concentrates, so that over time you fill a five-gallon bucket, and then maybe even a fifty-five-gallon drum, with black sands, magnetite, ilmenite, rare earth elements (REEs), and gold, you will be rewarded in the long run.
Either way, your long-term goals are your own.Very few prospectors are simply in it for the money, looking at this as a way to become a millionaire overnight. Some of us just like to get out of town, camp in the mountains, and enjoy the spirit of the outdoors. Some people like to work up a little sweat and appetite, improve their health, and learn a little. Some of us like to solve problems and run machinery, and enjoy the challenge of keeping a pump going or making sure the sluice is running right. Still others like the wildlife, the scenery, and the historical importance of the Wild West, and bring back their riches as photos and videos. In each case, if you toss in a little gold fever as motivation and stay scientific about your sampling and exploration, you will prosper far and above the value of your recovered material.
Still, a nice payday is always a treat. One sure way to reach that goal is to keep trying. Keep practicing, keep exploring, and keep getting out in the field. Another truism that seems to hold is that the farther away from civilization you get. the better your chances.
The development of a load/placer mine and the selection of the proper gravity recovery plant is more difficult than most people realize. Television shows have glamorized mining making it look like anybody can start a mine with little to no experience. What people dont realize is that mining is a structured engineering discipline taught at university. Just as you should not build your own bridge without knowledge of civil engineering, you should not think becoming a miner is a simple task. If you have no experience in the mining field you need to get educated about the process before you embark on this adventure. We have compiled a basic guide to assist in that process.
The terminology used for this type of mining is often interchanged. The term for the type of deposit under consideration is alluvial. Alluvial deposits are formed when the gold has migrated from its original deposition by weathering to a new location often inactive stream beds or in historic watercourses now overlain by sediments or glacial sediments.
In general Placer Mining is typically the recovery of gold from stream sediments through the use of dredges and sluices or other gravity means. Load mining generally involves the stripping of an overburden layer (soil) to uncover the underlying gravels that contain the gold. These deposits are often mined with mobile equipment and the ore trucked to a gravity treatment plant.
1. Permitting am I allowed to disturb the land excavating pits, leaving tailings behind, water usage, noise, air quality. In most cases you are not allowed to simply start mining even on your own land without the proper permits.
2. Resource estimation how much gold is present (grade and tonnage) and what does the deposit look like over burden depth, ore depth, gravel size. Generally, a placer resource is established by drilling or augering holes around the deposit to delineate the extent of the gold. This is often combined with field gravity recovery testing to provide an estimate of the recoverable grade.
6. Mine plan do you have a mine plan where are you going to mine first, where is the overburden going to be placed, where are the tailings going to be placed, is the plant going to be in one spot or moved during the mine life, what are the haulage distances. Is this a seasonal operation?
Mine Conditions Where is your project located? terrain, climate, infrastructure variables How large is your concession? Is a mobile or fixed plant right for this application? How many yards/hour (m/hr or tons per hour) do you want to process? How much water do you have available (GPM or m/hr)? Is there power available from the grid or do you required generation?
Plant Characteristics Are you looking for a mobile machine that you move regularly or a stationary plant that you haul your ore to? What type/size of equipment will you be feeding the plant with (front end loader, dredge pump, other)?
Feed Characteristics Ore consistency: What is the estimated maximum boulder size (in, mm)? Is there significant clay present? What is your maximum gold size (mm or um)? Is there fine gold present, what is the typical size (um)?
8. Economic Model Once you have made some initial assumptions you need to develop an economic model (even a basic one) so that you know if the project is viable before you start. No matter what type of project you should try and establish some basic economics unless this is just going to be a small hobby operation where profit does not matter. There are a lot of assumptions required to develop the model and you need to be realistic in your assessment. Add contingencies for operating costs of 10-15% and 20-30% for capital costs.
