Enhanced Gravity Concentration for Precious Metal Recovery

cyclone underflow maximizes the precious metal units that the enhanced gravity concentration equipment sees per unit of feed. For a long time it has been assumed that cyclone underflow will consequently have the highest output of metal. 2) Slime Desliming ahead of gravity concentration devices that operate at 1 G or less is a well-proven technique.
