gravity concentration equipment for gold


Posted on November 17, 2018



Gravity Concentration | GekkoThe gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest.gravity concentration equipment for gold,Enhanced Gravity Concentration for Precious Metal RecoveryEnhanced gravity concentration technology has largely replaced jigging as the technology of choice in precious metal grinding circuits worldwide. The benefits of using a centrifugal field to concentrate both coarse and fine gold are well documented but the placement of these machines within grinding circuits is still evolving.
