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.

The IGR 10K Placer Gold Mining Plant is an A-La-Carte = Fully Customized Alluvial Mining Equipment. This means that the user can order components from a list of existing part numbers without paying for engineering designs. The user can select options at the time of purchase or add components in the field without obsoleting the components they may already have. A 100 TPH (2400 Tons per day) gold recovery system.
As alluvial and eluvial deposits vary greatly in feed size distribution and clay content, an alluvial/eluvial plant needs the capacity to process an extreme range of conditions. It is common in the equatorial regions of the world to feed a plant with a dredge and/or an excavator. This plant can handle the range of material and various feed options.
The IGR 10K A-La-Carte Placer Gold Mining plant will have the versatility to process a broad spectrum of conditions from clean gravel to laterite and saprolite clays. Alluvial Channel/Gravel conditions may involve 20% to 90% of the solids feed passing 2mm- and continuing to the concentrators. Clays may have 90% passing 2mm- and continuing to the concentrators. This plant will work in conditions of both gravel and clay. Plant throughput and efficiency will vary with the condition of the material.
The A-La-Carte structure of the plant will allow the client to purchase only the components they need. The modular design will allow the purchaser or operator to add or remove components without obsoleting that which they already have and without requiring engineering design.
An operator may choose to start with or without the scrubber. This decision will be made based on knowledge of the clay content and capital investment. As the user gains experience they may choose to add the scrubber or remove it from their system; this is A-La-Carte the client can add or subtract components at will without re-design. Additionally, the user may desire to add options such as DMS or Jigs for diamonds and/or cyclones for dewatering/de-sliming.
The plant can be fed by excavator/loader or land dredge. Our plant including the scrubber is ideal to be fed by a loader/excavator. When feeding by a land dredge the user may opt to leave the scrubber out of the system. The land dredge will do a decent job of dispersing the clay though not perfect. The land dredge also delivers slurry at maybe 15% solids by weight. This is considered very thin slurry for efficient scrubbing. Operators in some regions insist on scrubbing the dredge discharge. Field testing will provide the best information on your material.
Sepro/IGR always recommend sample testing. Met-Solv Labs offers a specific lab test for laterite and saprolite clays We will write a performance guarantee for our equipment based on lab testing. This analysis will determine the ideal plant for your regional material.
An operator will feed material onto the grizzly. A water monitor fluidizes/mobilizes the material allowing it to pass through the grizzly where it continues to either a scrubber or vibrating screen. It is the fluidizing action of the monitor that controls the feed rate of solids into the system. Clean gravels will mobilize easily with the monitor and provide the maximum flow rate of solids. Clay will require more water to mobilize the material allowing it to pass through the grizzly. A wider grizzly allows larger clay balls to pass. This keeps the solids to water ratio high which leads to maximum efficiency in the scrubber and maximum solids throughput of the plant.
This wash plant scrubber works best at 50% solids. A scrubber uses large rock as the grinding media. A scrubber will lift the solids to 1 oclock and drop the solids back to 7 oclock causing an energy intensive lifting and dropping action. It is the attrition of the rock on rock action that acts to disperse the clay. Clay processing is based on energy input and retention time inside of the scrubber. To scrub better, the operator can increase the retention time or literally add large rocks to the scrubber.
After the scrubber the material passes to a double deck vibrating screen. Typically the upper deck cuts at 12mm and the lower deck cuts at 2mm. These can be specified by the customer. The 2mm- passes to a slurry transfer pump and on to the concentrators. The 2 to 12 mm middling is recombined with 12mm oversize and pass to the oversize stacking conveyor.
A max of 90 tph of solids can be fed to each battery without harm to the system. A minimum of 6 tph of solids is recommended to each battery. The intent is to always use 6 concentrators regardless of the feed rate. The slurry water capacity of 700 gpm +/-10% is intended to remain constant regardless of the solids feed rated. No control system is required for the slurry water.
A Carousel Distributor is used to distribute the slurry from the head tank to the 6 active concentrators. The distributor also blocks the flow to the 7th concentrator allowing the operator to rinse the rich concentrate. An operator will manually rotate the distributor and operate the valves on each concentrator.
Tails are piped to a common tails launder and with an 8 flanged outlet. The launder is designed for gravity discharge. (Pumping the tails requires modification to the depth of the launder to avoid cavitation.)
All equipment is mounted on a single skid designed to fit in a 20 container. The skid includes a roof structure with corrugate roofing. The container will arrive with the majority of the assembly already complete. Some site assembly will be required. This includes erection of the portions too tall to fit in the container and installation of the roof panels.
The screen fractions can be processed separately if the customer desires. This would require an additional conveyor. Also, one may choose alternate screen apertures: a top deck at 30mm where the 2mm to 30mm fraction is passed to a DMS or jig for diamonds is an option. In this case only the 30mm+ would pass to the tails conveyor.
Gold concentrators are batch machines. This means you must occasionally divert the feed to rinse the rich concentrate. In a system with only 1 concentrator, you either by-pass to tails or to a tank/slurry pump that recirculates the slurry back to a head tank. A system having 2 concentrators would allow to you to always feed 1 out of the 2. This is inefficient. A system feeding 2 concentrators while rinsing a third, becomes financially viable when using the economical i350. A battery feeding 6 while rinsing the 7th is very efficient and cost effective. The iCON Rotary Distributor allows easy distribution of the slurry and sequential rinsing without complicated industrial valves and/or controls. The distributor is hand operated.

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.
