production of pure antimony xide and/or metallic antimony. The conventional technology for the production of metallic antimony from stibnite concentrates is primarily by oxidizing roasting to convert the stibnite into volatile antimony oxide (Sb 2 O 3), which is subsequently reduced to antimony metal with carbon [1]. Although this conventional
