Artisanal and Small-Scale Gold Mining Without Mercury

Centrifuges operate in cycles that can be preprogrammed or determined manually depending on the equipment and the material processed. After a cycle is completed, the miner can then extract gold from the ridges of the centrifuge vessel. For small scale centrifuges, cycles usually last around 0.5-2 hours.

Gold Recovery, iCON Gold Recovery, Gravity Concentrators

For example, one miner improved his recovery from 40% to 70% simply by screening his feed from 8mm to 2mm. No gold was lost, because his largest gold was around .5mm. The iCON method will improve your process by screening your feed to the proper size. This will reduce the volume of feed and increase the percentage of gold that you recover.
