Worldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners. The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from the whole ore.

To the alluvial gold mine, the gold exists in the form of monomer native gold, with size larger than 16t/m³. So, the most economical and effective way of mining alluvial gold is gravity separation. Alluvial gold mining equipment includes kinds of spiral chute, jigger, shaking table and centrifugal separator, etc.
Other point to keep in mind is the specific gravity of the magnetic minerals, usually they range from 4.5 to 6.5, these values are much lower than the specific gravity of gold, 19.3. The shaking table can be used to clean the concentrate from the spiral concentrator. Apparently you work in a lab.

Alluvial Mining, Placer Mining & Dredging. Alluvial miners often ignore the fine gold because sluices and jigs can't catch it. Depending on the size and shape of your gold a sluice may begin to lose gold at 40 mesh. Some alluvial mining deposits have 90% of their gold finer than this where enhanced gravity, iCON, is the only solution.
