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.
Operating a centrifuge takes skill as it must be tuned to the material it is processing. This is accomplished by adjusting feed grain size, rate of feed, rotation velocity, and cycle duration. Centrifuges can be more effective at concentrating gold than other methods of gravity concentration but are generally more expensive.
