Gold Processing Plant

Gold carbon-in-pulp(CIP) is a typical gold beneficiation process for the effective recovery of gold-bearing minerals with a high oxidation degree and low grade of raw ore. Gold CIP has become a widely used gold extraction method worldwide because of its advantages of high adsorption rate, high recovery rate, and low investment cost.
