gold wash plants for sale | portable gold mining equipment

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.

With the rising price of gold and the limited amount of mineable land, people are now focusing onthe recovery of fine gold. Some rivers of the world have been sluiced as many as 6 times, yieldingprofitable gold each time and demonstrating that traditional sluices can have very poor recovery.

A Land Dredge is an effective way to break up and transport clay. Through the action in the impellor and turbulence within the hose, the land dredge is one of the most economical means of dispersing and transporting clay.

The IGR 500-2 is ideal to use in conjunction with a 6 land dredge. The 2 cyclones can process 800 gpm of slurry. The 2 i350 concentrators can process 20 tph of -2mm solids with surges to 30 tph. Land dredges and sluices normally have a very thin slurry. The cyclones are used to remove the excess water and provide an efficient slurry density to the concentrators.

The i350 Concentrator operates efficiently at 10 tph solids with a max of 15tph of 2mm The dual 5 HP feed pumps have a capacity of 90 m^3/hr (400 gpm) of water at 15dynamic head each, for a total of 180 m^3/hr (800 gpm) at 15 dynamic head.

Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost-efficient process designs.

Based on abundant experiences on gold mining project, Prominer helps clients to get higher yield & recovery rate with lower running cost and pays more attention on environmental protection. Prominer supplies customized solution for different types of gold ore. General processing technologies for gold ore are summarized as below:

For alluvial gold, also called sand gold, gravel gold, placer gold or river gold, gravity separation is suitable. This type of gold contains mainly free gold blended with the sand. Under this circumstance, the technology is to wash away the mud and sieve out the big size stone first with the trommel screen, and then using centrifugal concentrator, shaking table as well as gold carpet to separate the free gold from the stone sands.

CIL is mainly for processing the oxide type gold ore if the recovery rate is not high or much gold is still left by using otation and/ or gravity circuits. Slurry, containing uncovered gold from primary circuits, is pumped directly to the thickener to adjust the slurry density. Then it is pumped to leaching plant and dissolved in aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed directly into coarse granules of activated carbon, and it is called Carbon-In-Leaching process (CIL).

Heap leaching is always the first choice to process low grade ore easy to leaching. Based on the leaching test, the gold ore will be crushed to the determined particle size and then sent to the dump area. If the content of clay and solid is high, to improve the leaching efficiency, the agglomeration shall be considered. By using the cement, lime and cyanide solution, the small particles would be stuck to big lumps. It makes the cyanide solution much easier penetrating and heap more stable. After sufficient leaching, the pregnant solution will be pumped to the carbon adsorption column for catching the free gold. The barren liquid will be pumped to the cyanide solution pond for recycle usage.

The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated onto cathodes of steel wool. The loaded steel wool is pretreated by calcination before mixing with uxes and melting. Finally, the melt is poured into a cascade of molds where gold is separated from the slag to gold bullion.

Prominer has been devoted to mineral processing industry for decades and specializes in mineral upgrading and deep processing. With expertise in the fields of mineral project development, mining, test study, engineering, technological processing.

Since 1972, KCA has fabricated portable or modular carbon adsorption, carbon desorption, carbon strippingand Merrill-Crowe plants. KCA's plants have earned an outstanding reputation for quality, simplicity, ease of start upand fail-safe operation. Modular plants can be constructed for gold operations treating up to 4,000 tonnes of ore per day. Above that size, plants are built on-site.

The Al Hajal plant (also used at the Hamdah project) in Saudi Arabia is a complete plant for production of dore gold bars, mounted in a 6-meter (20-foot) container. The smelting furnace can be seen on the concrete slab on the right side of the photo. This size plant is ideal for heap leach tests or very high grade small operations (producing up to 400 tonnes of ore per day).

This seven million tonne gold heap leach is located at an altitude of 4600 meters (15,000 feet) in northern Chile. Through its associated company, Decommissioning Services LLC, KCA provided engineering, procurement and construction management (EPCM), and then subsequently entered into a 2-year contract to provide complete project operations management services.

The heap was an accumulation of ore from an on-off heap leach formerly operated by a large international mining corporation, Billiton. Based on an evaluation of exploration drillholes into the heap, KCA was able to show that washing would mitigate an environmental problem (high residual cyanide) and recover significant amounts of gold and silver. Under contract to the client, KCA designed and installed a stabilizing butress, a recovery plant, and a complete heap piping system. During three years of "washing", precious metals production exceeded 30,000 ounces of gold, essentially in agreement with the projection made by KCA at the start of the project. The client realized an operating profit on this environmental cleanup project.

The Getchell, Nevada, Carbon ADR plant consists of a five-stage vertical tower adsorption column. Desorption and electrowinning take place inside the trailer. KCA has built several tower column plants, which offer portability and compact size.

The ore treated in this 1200 ton per day heap leach was unique in that it was high in oxidizing sulfides, including very reactive arsenic sulfides (orpiment and realgar). Solution exiting the heap was colored deep blue with iron ferrocyanide - a classic indicator of oxygen deficiency. Nevertheless, gold recovery was good, and by controlling cyanide addition rates the consumption of cyanide was maintained within economic limits.

KCA provided the lab testing, design, engineering, and construction management of the heap leach and recovery systems. KCA supplied the agglomeration drum and conveying and stacking systems, and a 180 gallon per minute five-stage tower column plant for carbon adsorption. In 1988, this plant was repurchased by KCA and re-installed at the Atlas Gold Bar mine.

KCA conducted laboratory investigations on ore samples from the deposit, provided conceptual design of heap leach pads and ponds, and developed the operating philosophy. KCA also provided the design, construction, and start-up of a complete gold adsorption-desorption-recovery plant rated at a production capacity of 300 tons per day. Direct capital and operating costs were repaid within the first season.

All operations needed for recovery of gold and silver from solution onto activated carbon, desorption, and electrowinning of metal bullion, are included in a 40-ft (12 meter) trailer or shipping container.
