    Extracting Precious Metals MW MINING & INSPECTIONS,

    The roasting of sulfide’s ores is often the first step in the oxidation needed to extract precious metals from concentrates. In roasting, the ore concentrate is treated with very hot air causing an oxidation reaction. During roasting, the sulfide is converted to an oxide, and sulfur is released as sulfur dioxide, in the form of a gas.
