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.

small gold processing plant

small gold processing plant

The problem aSmall Gold Processing Plant can solve is for the need to to provide a small, relatively simple and inexpensive gold mill that will operate at a reasonable profit with a minimum of supervision. The limited availability of skilled operating personnel, availability of water and local power, high cost of transporting ore and expense of building, operating and maintaining such a mill have been taken into consideration in developing the flowsheet. A primary objective is to provide a mill having sufficiently low power and water requirements as to be supplied locally.

The flowsheet was developed for a siliceous ore with a high percentage of the gold present in a free milling state. In addition some gold bearing sulphides are present which require the inclusion of flotation in order to obtain maximum recovery. Most of the goldis, however, recoverable in bullion form for shipment to the mint. The gold tied up in the flotation concentrate is shipped to a smelter, although in remote areas a small batch cyanide plant may be used to extract the values and thereby eliminate the shipping and smelter charges.

Single stage crushing for the average small mill (100 tons or less) is adequate. The crushed ore at approximately minus 1 inch is wet ground in a Ball Mill to free the gold and sulfide values. Grinding is in closed circuit with a classifier and in this case a 48 mesh grind was necessary.

To trap the heavy free gold in the grinding circuit a Mineral Jig is placed between the ball mill and classifier. This recovers the gold just as soon as released and avoids its accumulation in the bottom of the Classifier or Ball Mill scoop box. The high grade gold concentrate from the jig is ground in batches and amalgamated in a Amalgamation Unit. The residue from the unit is collected, dewatered, and saved as it usually contains sufficient value for retreatment or shipment to a smelter.

Amalgamation plates are shown in this flowsheet to recover the very fine gold which may escape the jig and overflow the classifier. Amalgam from the silvered copper plates is collected periodically and retorted along with the amalgam recovered from the amalgamated Jig concentrate. Corduroy blankets may be used in place of the plates. The heavy mineral concentrate is ground and amalgamated with the jig product.

The ground pulp after jigging and amalgamation will usually contain 20 to 25% solids which is ideal for flotation feed. This pulp passes to a Conditioner where reagents are added to activate the sulphides and possible tarnished gold values. After conditioning the pulp flows through a Sub-A Flotation Machine of the cell to cell type. The flow arrangement is typical for small plants where the ratio of concentration is high. If more cleaning is necessary, the feed may be introduced into the second cell and the final concentrate taken off Cell No. 1. Reagents for gold flotation are simple and usually consist of soda ash, a xanthate, and a frother.

All concentrates including the amalgamation residue are pumped to a Disc Filter for dewatering. Filtering may be direct without thickening. If the quantity of concentrate is appreciable and filtration rates low, a Thickener ahead of the filter is advisable.

Flotation tailings are finally tabled for recovery of oxidized values. This product may be added to the flotation concentrates, or if some free gold is present, it may be amalgamated along with the Mineral Jig concentrate. The Table also serves as a pilot control of the mill circuit both as to grind and recovery.

In this example the concentrates from the Mineral Jig and Table were combined and amalgamated to give the above recovery in amalgam form. With amalgamation plates in the circuit as shown, the recovery of gold in bullion form should approach 80%. The balance of the recoverable gold is in concentrate form for shipment to the smelter. In the example shown the combined shipping product (residue plus flotation concentrate) assays 6.45 oz. gold per ton. From 50 tons milled, 2.88 tons of concentratesare produced.

The developed flowsheet provides a Small Gold Processing Plant which can be efficiently operated by one operator per shift or with a helper if local requirements so dictate. Power requirements are such as to be available from a portable generator and water requirements are held to a minimum.

Portable gold mining equipment and process flow 1. Feeding: dredge pump, hopper feeder with vibrating grizzly bar. 2. Washing and screening: usually use rotary scrubber, gold trommel, sand washing machine, vibrating screen, etc. 3. Beneficiation: gold centrifugal concentrator, shaker table, sluice box, mineral jig. 4. Water supply 5. Tailings 6. Mobile System: Composed of chassis and traction steering two major components, 4 axes 16 tires, 4 mechanical legs support centrifuge, can be turned in situ 180 degrees, easy to move to the workplace. Working principle1. Dry gold mining Dry land mobile gold wash plant with rubble tyre, easy to move on, can separate placer gold from ancient river, dry beach sand. Dryland gold mining usually use trommel screen combines the small gold jig and gold sluice box into a single mobile gold recovery plant to process placer gold, monomer lode gold. This type of small scale gold wash plants has a light weight, easy to maintain, low cost. 2. River gold mining The river gold panning equipment, mostly as the gold dredging ship floating on the water, it is a multifunctional placer mining equipment that combines excavation, ore washing, beneficiation, tailings disposal, and power supply, water supply. River gold dredger can work at stream, river, offshore, beach side, etc. But as for small gold wash plant, the cost of the gold dredger may be a huge part. How to build a small gold wash plant? Using dredge pump pumping the river bed fine sand to the near land portable gold trommel, wash and classify the undersize material to gold centrifugal concentrator and shaker table.
