 Process of Gold Extraction

1.Feeding Alluvial Gold Raw Material

Gold mining need a feeding device, like a hopper. If the raw material has big rock, then hopper should have a grizzly.

Feed by Excavator or Loader, it use different design

2. Sieve Gold and Sand

To ensure providing normal size raw material, material need to be sieved first. There is many sieving machine, like trommel, vibrating screen etc. For alluvial gold, trommel is best. Trommel are simple structure, high efficiency and sieving completely. It's the important sieving machine for alluvial gold mining process.

3. Separation

After sieving, the material should be feeded into separation machine. Gold specific gravity is about 19, sand specific gravity is about 3.5. The Principal Methods of alluvial gold (placer gold) are gravity dressing. Now the most popular gold mining gravity equipment are: Sluice, Concentrator, Shaking Table. In recent years, concentrator (centrifugal machine) is widespread used, and the effect is good. For improving gold mining condition, some institution, colloge and manufacuturer researched some high efficiency gold mining equipment. For instance, cross flow belt chute, short conical hydrocyclone, vibration chute, fluctuate sluice and etc.
Flotation mining, magnetic separation mining, electrostatic separation mining, amalgamation and chemical method are mainly used for separating ore concentrate.

After sluice or concentrator, it's gold heavy concentrate now. It's time to refine. Shaking table or mercury amalgamator is used for this. After shaking table or mercury, the gold purity is about 85%-90% (20K-21K gold). Due to alluvial gold mining process technology, that's the highest purity. For small gold mine, we suggest clients sell it directly. Because 99.99% refine is not economy for small miner. Or you can also use chloroazotic acid. Jacketed Pilot Plant Reactors is a good device. It's a circulate closed machine.

4. Refine Gold

After sluice or concentrator, it's gold heavy concentrate now. It's time to refine. Shaking table or mercury amalgamator is used for this. After shaking table or mercury, the gold purity is about 85%-90% (20K-21K gold). Due to alluvial gold mining process technology, that's the highest purity. For small gold mine, we suggest clients sell it directly. Because 99.99% refine is not economy for small miner. Or you can also use chloroazotic acid. Jacketed Pilot Plant Reactors is a good device.
