Gold Sulfide Roasting Process
Gold sulfide (Au₂S) roasting method is a high-temperature oxidation treatment method. Through high-temperature roasting, the sulfur element in the gold sulfide is converted into gaseous sulfur dioxide (SO₂), and the gold is converted into an extractable oxidized state or metallic gold. This process is mainly used for the pre-smelting treatment of gold sulfide ore or gold-containing sulfides.
