Sulphur Refining of Gold - Mineral Processing & Metallurgy

Refining using Sulphide of Antimony. This process is also some centuries old, and is based on the fact that when gold-silver alloys are melted with sulphide of antimony sulphide of silver will form, and the gold will alloy with the antimony. Au + 6Ag + Sb2S3 = Au + 2Sb + 3Ag 2S. Copper and other metals will also be removed by this process.
