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:
