Alluvial Gold Washing Plant

Alluvial gold washing plant offer a simple, efficient and economical solution for upgrading a wide range of materials and optimizing subsequent recycling process steps. This screening method helps reduce operating and investment costs and improves product quality, while allowing rapid and high-volume processing. This material is then passed to downstream process equipment, which can take various forms such as centrifugal concentrators, sluice box, shaking table, jigs, etc.

Our alluvial gold washing plant is suitable for various types of gold raw materials: placer gold/river gold/alluvial gold/gold tailings, etc. The main processing of gold includes feeding, washing, screening, roughing, final selection, and refining. Since gold is much denser than other minerals, gravity separation is mainly used.

Gold Mining Process:
1. Feeding: There are a variety of feeding methods, depending on plant and material conditions. Choose from vibratory hopper feeders, hoppers, industrial conveyor belts or direct feed from wheel loaders and excavators. Usually some screen bars are made on the feeder or hopper to remove large waste rocks.

2. Screening: After washing, some larger waste materials need to be sieved out, and the slurry under the sieve enters the next machine. This process can use a drum sieve.

3. Primary beneficiation: This process is crude gold beneficiation, which can use gold centrifugal concentrator or jig gold concentrator. Their concentrate will go to the final concentrator.

4. Final selection: The concentrate selected by the jig or centrifuge enters the shaker for final gold selection, and high-purity gold can be obtained.

Tailings recovery: Gold mines are often used to recover tailings from centrifuges. This way you can get more gold.

5. Refining: If some customers need very, very high-purity gold and need to smelt it into gold bars for sale, you can use a gold smelting furnace to smelt gold powder into gold bars.

	Feed system Hopper size: Provide customization The hopper is made of 6mm thick high manganese wear-resistant plate, and the bottom will be reinforced with channel steel. With grizzly. With worker operation platform Remark: Water spray pipes along hopper sides Function: to feed the materials evenly to the scrubber and trommel
The grizzly is welded by round steel with a diameter of 35 mm, and the gap can be made according to requirements. If there are big stones, it can be made of I-beam (the contact surface is wide, which will affect the feeding).
