| titleOfInvention | Antimony sulfide concentrate smelting process |
| abstract | The invention discloses a novel antimony sulfide concentrate smelting process, which comprises the steps of potential-controlled enhanced leaching, hydrolysis, potential-controlled arsenic precipitation, dechlorination, enhanced reduction smelting and the like. Antimony sulfide concentrate is subjected to potential-controlled shearing and enhanced leaching to obtain a leaching solution and leaching residues, and the leaching solution is reduced and then cooled to separate out elemental sulfur. Diluting and hydrolyzing the sulfur-separated liquid to obtain antimony oxychloride and hydrolyzed liquid. After hydrolysis, the liquid is controlled to remove arsenic by potential and then returned to the hydrolysis preparation liquid for use. Dechlorinating antimony oxychloride to obtain crude antimony oxide and dechlorinated liquid. And electrolyzing the dechlorinated solution through a diaphragm to obtain caustic soda and chlorine, wherein the caustic soda is reused for dechlorinating crude antimony oxychloride, the chlorine is reused for controlling potential leaching, and the crude antimony oxide is subjected to low-temperature molten pool enhanced reduction smelting to obtain refined antimony, or is treated by a plasma furnace to obtain high-purity antimony white. The invention can eliminate low-concentration SO from the source 2 Pollution, avoiding the production of arsenic alkali residue, and has the characteristics of cleanness and environmental protection. |
