· 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: * Pressure Oxidation: Thickened slurry is pumped into autoclave. It faces high pressure (20-50 bar) and high temperature (180-225°C) with oxygen.

· Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where <a title="Gold
