• Antimony
• Hydrometallurgical process
• Stibnite concentrate

This study aimed to introduce a comprehensive process for separating and recovering antimony from a complex stibnite concentrate. Antimony is first leached through a chlorination-oxidation procedure to obtain SbCl3 solution. Antimony is then recovered in the forms of cubic crystal Sb2O3 (99.9%), high-purity cathode antimony (99.98%), crude cathode antimony (99.7%), high-purity SbOCI (99.9%), and crude antimony (>99%) through the following processes: hydrolysis, membrane electrowinning, hydrolysis-low temperature smelting, and hydrolysis-washing.
