Gold CIP Processing Plant, Gold Carbon-in-Pulp Process

The gold CIP (Carbon-in-Pulp) processing is widely used to extract gold from ore. It mainly involves using activated carbon to adsorb gold from a cyanide solution, then eluting and regenerating the carbon for reuse. It is mainly suitable for beneficiating gold-containing oxidized ore with high slime content and containing carbon ore.

Gold Processing Steps 101: Essential Guide

Some gold ores are refractory ores. They are difficult to process with regular cyanide leaching. This is because sulfide minerals encapsulate the gold particles. To address this, a pre-oxidation step is required. It breaks down sulfide minerals and exposes gold particles to the leaching stage. There are a few pre-oxidation methods:
