One-step extraction of antimony from low-grade stibnite

2015-4-15  The extraction of antimony from low-grade stibnite in eutectic Na 2 CO 3 –NaCl molten salt using ZnO as a sulphur-fixed agent was studied. The results of the experiments on the reaction mechanism indicate that the reaction courses of antimony and sulphur were Sb 2 S 3 →Sb 2 O 3 →Sb and Sb 2 S 3 →ZnS. Sulphur was fixed in the form of ZnS, while molten salt did not react with other ...
