This complete process plant is for recovering gold by gravity concentration and froth flotation. This commonly applies, but is not limited to, ore deposits containing GRG gold and sulphide minerals rich in gold (such as: Pyrite, Copper). This process will also recover silver associated with sulphide minerals. This simple metallurgical concentrator includes single

While froth flotation and cyanide leaching both play major roles in gold recovery, the benefits of using gravity concentrators cannot be understated. As a low-cost addition to any circuit, it helps optimize the recovery process and mitigates processing risks due to ore variability. Here are just a few advantages of adding gravity concentrators
