classification and centrifugation | flsmidth

A cyclone, also known as a hydrocyclone, is a centrifugal device with no moving parts. It can be used to concentrate slurries, classify solids in liquid suspensions, de-grit liquids, and for washing or cleaning solids. A hydrocyclone can perform ultra-fine separations and handle large-volume feed streams with high solids loading.

Cyclones frequently are used as an efficient and effective means to protect or pre-treat material, to improve the performance or decrease the cost of downstream equipment, such as centrifuges, filters, and screens. Cyclones are also used in conjunction with thickeners, clarifiers and strainers. Heavy Media Separation (HMS) or Dense Media Separation (DMS) cyclones (hydrocyclones) are designed specifically for cleaning applications. Within the cyclone, weight and gravity separate the lighter material from the heavier material, as the medias buoyancy effect forces the lighter solids to the cyclones centre, where they float upward and out through the vortex. The heavier, denser material spirals to the outside of the cyclone, and sinks down towards the apex exit.

To meet your requirements, we offer a comprehensive range of centrifuge systems for coarse and fine material separation and dewatering, including screw-style and basket-style, our popular screenbowl centrifuge, and a variety of solidbowl centrifuge configurations.

Centrifuges utilise the principles of centrifugal force the force from spinning that moves material away from the machines centre to enhance the force of gravity on particles and achieve separation based on the particles density.Mining and industrial centrifuges typically comprise a cylindrical or cone-shaped bowl or tube, rotated at high speed. Material is fed as a slurry toward the centre of the unit, and due to its rotation, is forced outward. The slurry is held against the outer wall of the container, and the water can filter through the solids bed and exit as concentrate. One of various methods of removing solids (depending on the centrifuge type) is then employed to move the solids to the discharge area.

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, magnetic, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.

Dense media separation utilises a medium with a density in between the density of the ore and the gangue (commercially worthless) particles. When introduced to this medium, particles either float or sink, depending on their density, as relative to the medium. Separation using this method relies solely on differences in density, without relying on other characteristics such as particle weight or shape.

Heavy media drum separation (HMS) also known as dense media separation, is a process used to separate materials that have different specific weight. A heavy media fluid of the correct density is pumped and kept in circulation inside a rotating drum. The material to be separated is immersed into the fluid, which allows lighter particles to float, while heavier ones sink.

Our drum separators and plants combine high efficiency with a unique feature: All mechanical drive parts are external to the drum with no buckets, chains or other moving parts located within the processor. This design significantly reduces wear caused by abrasive media solids, minimises replacement costs, and greatly simplifies maintenance.

hydrocyclone working principle

hydrocyclone working principle

The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE.

Unlike the rake and spiral classifiers, the overflow of the cyclone is the exit point for the fine material instead of the other way around as it is in the case of the other two. Extending from the overflow discharge into the body, which is the feed entry point of the cyclone, is the VORTEX FINDER.

This is simply a length of pipe, its purpose is to provide a point of separation between the coarse and fine material. A better explanation will be possible once we begin explaining how it works. Next in our list of cyclones components is the UPPER and LOWER CONE, not all hydrocyclones havethis section divided into two cones. Some are designed thisway do to make repairs easier, and to isolate wear points, Their function is to help create a VORTEX.

This is done by guiding the slurry to the underflow at the same time presenting a smooth surface that will not restrict the generation of the CENTRIFUGAL FORCE that makes classification possible. Connected to the lower cone is the APEX. The apex is the discharge point of the cyclone, this discharge is referred to as the UNDERFLOW. The material that exits at this point will be the material that requires further grinding. The last part of the cyclone is the cyclone SKIRT. It is there only to limit spillage and splashing it isnt important to the operation of the cyclone.

I would suppose you are asking yourself, why and how does this piece of equipment separate the different sizes of rock? To answer that, we have to get into the operational theory of the cyclone. To start with, the slurry is directed into the cyclone along the wall of the body. Due to the ore being pumped, the slurry has VELOCITY. It is this velocity and point of entry helps in creating a spiral path around the outside of the body, the upper and the lower cone.

The entrance to the cyclone was designed this way to allow the incoming feed to help generate and not interfere with the spiral path that the ore must take inside the cyclone. The centrifugal force (the central Hydrocyclone Working Principle) that is generated by this spin, forces the bigger particles outwards towards the wall of the cyclone. If you were able to do a cross section of a cyclone while it is operating, you could see that the ground rock will become finer the closer that you get to the centre of the cyclone.

In all hydrocyclones there are two outlets, one for thecoarse material, this is the APEX, and the other for the finematerial, which is the VORTEX FINDER. The purpose of the Vortex finder is to separate the fine material from the coarse as it spirals around the vortex. The WIDTH of theVortex finder will determine how far into the coarsermaterial the separation point will be.

The Volume of slurry that is being fed into the cyclone must not exceed the capacity of these two outlets that allow it to escape. The size of the apex and the vortex finder is crucial. If the apex of the cyclone, like the size of the drain in your sink, is made smaller it wont allow as much slurry out of the underflow of the cyclone. This will cause the vortex to be smaller the internal volume of the slurry inside the cyclone will be greater and the amount of material that the vortex finder separates to become part of the overflow will be increased. As it is the DISTANCE across the vortex finder that determines where in the vortex the ore flow is separated at, the SIZE OE THE APEX will determine the degree of classification that the ore will be subjected to.

The size of the apex in relationship with the volume of slurry that is being fed to the cyclone, will create and maintain the PRESSURE NECESSARY to force the fine material out of the cyclone. The greater the pressure the greater the volume of overflow. To increase the overflow requires either a higher volume fed to the cyclone or a smaller underflow discharge opening. As the pressure in the cyclone climbs the amount of coarser material in the overflow increases. The reason that this pressure is generated is because the volume of the feed is greater than apex discharge capacity. The pressure is generated as the volume of slurry is built up over the apex.

These three factors then become your operating Variables when dealing with cyclones, APEX SIZE, the SIZE of the VORTEX FINDER, and the VOLUME of the feed. The CYCLONE PRESSURE becomes a control indicator for the adjustment of the apex size and the volume of the feed. The vortex finder is a FIXED VARIABLE, meaning that it can be changed to affect the sizing of the overflow, but not as a normal operating practice. The cyclone must be removed from service and taken apart to make that adjustment.

If the variables become unbalanced to the point where the pressure is too high, the cyclone will overload. What this means is that when a vortex is generated, an air column is formed in the center of the vortex. If this air column collapses, the velocity of the spiral will decrease far enough to lose the centrifugal force that causes the ore to classify. As the internal pressure of the cyclone represents the volume of slurry that is in the cyclone it only follows that the reason that the air column should collapse is that there isnt room left in the cyclone for the air.

If the variables become unbalanced in the opposite extreme then there wont be enough pressure to cause an overflow. Either the volume will be too low or the apex size too large. This will result in all of the feed being discharged out of the underflow. By what you have just learned it is apparent that to maintain an even pressure on the cyclone is very important. If the cyclone is dependent on pressure to function effectively then a constant pressure would ensure positive control over the classification of the ore. This means the pump that feeds the hydrocyclone is very important to the effective working of that hydrocyclone.

To understand how pumps work we will have to leavetheir relationship to cyclones until we have discussed their components and functions. Once we have finished discussing the pumps by themselves, we will come back to this relationship and explain the other variables that effect the performance of these two machines.

spiral classifier or hydrocyclone - grinding & classification circuits - metallurgist & mineral processing engineer

would you please complement your "answer" with good reasons and comparisons with spiral classifiers and cyclones? Am looking for technological advantages and capital cost comparisons. You must have supporting data in separation efficiency improvements & performance of aDerrick screen to carrying it purchase price?

In addition to operational advantages, cyclones are able to differentiate between equal size particles of varying specific gravity. The high specific gravity middling particles are preferentially classified to the cyclone underflow by the high centrifugal forces developed in the cyclone, and returned back to the mill where the valuable mineral fraction can be liberated. The lighter gangue particles leave the circuit directly as cyclone overflow. This benefit is especially important in low grade porphyry copper ores where the preferential classification of the middlings results in a favourable compaction of mineral values within a very narrow size range. The concentration of copper in a typical cyclone overflow is highest in the 43 x 10 micron fraction, which corresponds to the highest mineral recoveries in the rougher flotation cells. Cyclones in a grinding circuit shape the size distribution of the valuable minerals so a large proportion falls within the range associated with high flotation rates.

The preferential classification benefit of cyclones is further illustrated in Table 2 which compares the metallurgical results of cyclones versus spiral classifiers in a copper grinding circuit. The cyclone produced an overflow product containing more copper in the finer size ranges where it will be subject to higher recovery in flotation. Table 3 summarizes results of cyclones versus classifiers. The copper tails dropped from 0.32% with the mechanical classifiers to 0.28% with cyclones. In addition, the higher circulating load produced by the cyclones resulted in increased circuit capacity while producing the same grind at a higher overflow density.

A friend familiar with this told me themain problem with spiral classifiers is the cutsize is directly proportional to retention time (flow rate, Stoke'slaw, that sort of thing). To get a fine cut size requires flow ofalmost zero = the finer you want to cut, the lower the flow and density required.

The principal use of mechanical classifiers has been in closed circuit wet grinding; however, this application has been widely displaced over the past few decades by the hydrocyclone. The hydrocyclone installation, including its feed pump, offers lower capital costs and requires less floor space.

However,these advantages of the hydrocyclone are being gained at the sacrificeof some of the advantages of the mechanical classifier. The mechanical classifier requires less power and has lower maintenance costs thanthe hydrocyclone and its feed pump. The underflow product fromthe mechanical classifier can have a higher solids content and contain less entrapped undersize particles than the comparable product fromthe hydrocyclone. Consequently, it is capable of operating at a higherclassification efficiency. A reduced circulating load results underthese conditions in a closed-circuit grinding application.

The proper selection of mechanical classification equipment requires that the properties of the solids and liquid are adequately defined. The following descriptive information regarding the solids is desired: feed rate, chemical and physical composition, density, temperature, size analysis, and desired separation size.

shaking table | henan deya machinery co., ltd

Working principle: it is used as a gravity separation device to sort fine materials. The shaking table separation depends on the combined effect of mechanical asymmetric reciprocating motion and thin water layer on the sloping table surface, so that ore particles on the table get loose and move to different layers and zones, and then the minerals are separated according to different densities. It is widely use for separating Gold, Manganese, Chromite, Copper, Iron, Titanium, Zircon, Tungsten, Tin,Tantalum, Barium, Lead, etc.

design principle of classification beneficiation,classification equipment,grinding machine | prominer (shanghai) mining technology co.,ltd

Classification is the process of dividing a group of particles into two or more particle size levels based on the difference in the sedimentation speed of the particles in the moving medium. It is generally applied to fine-grained materials. The movement form of the medium in the classification equipment includes vertical upward flow, approximately horizontal flow and rotary movement. The medium can be water or air. The classification using air as the medium is called wind classification. When the materials are classified in the rising water flow, the particles with the settling speed greater than the rising water flow speed will sink in the classification equipment and become sedimentation products. The particles with the settling speed lower than the rising water flow speed will be carried out from the upper part of the classifier by the rising water flow. It becomes an overflow product; the particles whose sedimentation speed is equal to the ascending water flow speed theoretically have a distribution rate of 5000 each in the sedimentation and overflow. The particle size of such particles is called the separated particle size.

The sedimentation form of the particles in the classification equipment generally depends on the volume concentration of the particles in the equipment. The classification with a smaller volume concentration is the free sedimentation classification, and the classification with a larger volume concentration is the interference sedimentation classification. Since the interference sedimentation velocity of particles is less than the free sedimentation velocity, the rising water flow required for interference sedimentation classification is less than that of free sedimentation classification, which can save water and obtain a larger concentration of sedimentation. The production capacity of the classification equipment is also Be improved.

However, because the interference sedimentation ratio is greater than the free sedimentation ratio, during interference sedimentation classification, the sedimentation will contain more fine and heavy particles, which will affect the accuracy of classification. Therefore, when the classification accuracy is required to be high, the interference settlement classification is not suitable. The accuracy of particle classification is not only affected by the size of the particles, but also by the density and shape of the particles.

(1) Hydraulic classifier, such as Yunxi type hydraulic classifier box, sieve plate type hydraulic classifier, etc. This type of classifier is mainly used for grading before reselection, and also for desliming.

(2) Mechanical classifiers, such as spiral classifiers. This type of classifier is mainly used for pre-classification, inspection classification and control classification during grinding, and is also used for desliming or dewatering.

The type of mining relates to hard rock,eluvial, or placer; alluvial deposits. The capital budget you have to invest in buying your equipment with dictate the scale at which you want to mine and influence the long-term operating costs of your mining operation.

Since most of the information online provides lists of gold mining equipment for amateur level mining with equipment like: gold pans, metal detectors, mini sluice box, blue bowl, geologist rock pick, soil scoop, hand screens/classifiers. The items listed just now fall closer to gold prospecting tools and equipment than actual mining.

I will present here what I consider are major equipment lists for 3 types of mining operations. Remember now, a metallurgist is writing. This will not be flawless and since my speciality is process equipment, that is mostly what will be discussed.

Some amateur level gold prospecting equipment such as metal detectors are often classified as mining equipment by small miners/prospectors operating as a hobby. These items include but are not limited to:

sasa - central asia metals

sasa - central asia metals

CAML took 100% ownership of the Sasa underground zinc-lead mine in November 2017. The mine is located in north eastern North Macedonia, approximately 150km east of the capital city, Skopje, and 10km north of local town, Makedonska Kamenica.

The Sasa deposit was discovered during a period of exploration between 1954 and 1965. Trial mining commenced in 1965 and, in 1966, the mine commenced commercial production as a state-owned entity. The mine closed in 2002 and was placed into bankruptcy due to lack of funding. The Solway Investments Group subsequently purchased the mine, invested in new equipment and operations resumed in 2006. Solway Group later sold the mine to Fusion Capital and Orion Mine Finance Group in 2015.

Sasa lies within the Serbo-Macedonian Massif, which hosts a large number of lead and zinc deposits and extends through Serbia, North Macedonia, Bulgaria, eastern Greece and into Turkey. The mines Svinja Reka and Golema Reka deposits are located on the eastern flank of a copper molybdenum porphyry deposit at Osogovo. Mineralisation occurs as stratiform deposits hosted predominantly by schists and marbles at Svinja Reka and by gneisses at Golema Reka. Hydrothermal fluids and bedding parallel faulting are responsible for the metasomatism of the host sediments that produce the skarn and base metal mineralisation. The deposits are well defined lenses of lead zinc silver mineralisation, which dip at about 35 degrees and range in thickness from 2 metres to 30 metres.

Sasa is an underground zinc and lead mine that produces approximately 820,000 tonnes of ore each year. Accessed by adit, the Svinja Reka deposit is currently mined using a sub-level caving method, which utilises the geotechnical characteristics of the weak hanging wall to allow the rock to cave naturally into the void remaining after ore has been blasted.

Main haulage levels are at 80 metre intervals, with sub-levels every 7 metres. Ore drives are typically 3.5 metres by 3.5 metres. Ore is mined using a top down approach without backfill. Ore is drilled using single boom jumbos, blasted and then excavated with underground loaders.

From the second half of 2022 the Sasa team will transition to a new mining method, cut and fill stoping, with approximately 90% of ore being extracted using this method by 2024. The voids will then be backfilled with paste material containing tailings to provide support, rather than allowing the roof to cave as is the case with the current sub-level caving method.

Once blasted, 70% of the ore is then sent via ore passes to the 830m level where it is transported by rail wagons to the Golema Reka shaft for hoisting, and the remaining 30% is hauled to surface via the adit.

Once at surface, ore is then crushed in three stages. The milling circuit then involves two rod mills, followed by spiral classifiers and then two ball mills to ensure material is the appropriate size for liberation by flotation at approximately 74 microns.

The processing plant then operates both lead and zinc flotation processes, producing separate concentrates that are filter pressed to produce products containing 5-9% moisture. Silver is also produced and this reports to the lead concentrate. The lead concentrate contains c.73% lead and the zinc concentrate contains c.49% zinc. The concentrates are stored in two separate bays before being loaded into haulage trucks for sale to smelters.

A Life of Mine study was commissioned in order to investigate the efficiency of operations at Sasa, including a review of the current sub-level caving mining method, and to determine recommendations that would optimise productivity.

The study recommended the transition from sub-level caving to cut and fill stoping, a more selective mining method, that will not only result in maximum recovery of mineral resources, but will also enable safer operating practices as well as longer-term improvements to tailings disposal. The Cut and Fill Project has been approved by the Board and the transition to the new mining method will take effect in the second half of 2022, with approximately 90% of ore being extracted using this method by 2024. In order to move to cut and fill stoping and therefore ensure effective long-term operations for the life of the mine at Svinja Reka, several practical changes will be implemented at site.

Cut and fill stoping is a more selective mining method than sub-level caving, which is expected to achieve greater recovery of ore as well as reducing the dilution of ore with un-mineralised material. It is a bottom-up mining method involving drilling, blasting and mucking out of ore before filling voids.

The cut and fill mining method involves filling mined voids with a backfill paste material containing tailings to provide support, rather than allowing the roof to cave as is the case with the current sub-level caving method. In order to achieve this, a backfill plant will be constructed, along with associated reticulation pipework to transport this material underground. Tailings from the processing facilities will be sent to the backfill plant to be thickened and pressed to contain 80% solids, and then mixed with a slurry containing cement, fly ash and water to produce a paste of the appropriate consistency. This is then distributed underground to fill stopes.

Given that a major component of the backfill material will be tailings generated from the Sasa processing plant, it is estimated that over 40% of Svinja Rekas life of mine tailings will be stored underground. Approximately 30% of tailings will be stored in the current TSF4, and CAML is advancing studies with a view to dry stacking the remainder and therefore eliminating the need to construct further tailings dams in the future. The Company is firmly committed to the environmental and socially responsible disposal of tailings for the long term.
