Stibnite
Gold–antimony ores usually contain stibnite (1.5–4.0% Sb), pyrite, arsenopyrite gold (1.5–3.0 g t −1) and silver (40–150 g t −1). Several plants in the USA (Stibnite, Minnesota and Bradly) and Russia have been in operation for some time. There are two commercial processes available for treatment of these ores. •

Selection on the Process for Removing and Recovering
The main antimony phase of antimonial refractory gold ores is stibnite (Sb 2 S 3). Sodium sulfide is proposed as leaching agent to remove antimony from antimonial refractory gold ores . Meanwhile, sodium hydroxide is also used to prevent the hydrolysis of sodium sulfide. The main equations are expressed as follows:
