硫化砷矿合理利用的湿法氧化新工艺

摘要

A new technology of alkaline digestion,atmospheric oxidation for Changdu high-purity arsenic sulfide ore in Tibet was tested.The technological parameters such as oxidation temperature,catalyst dosage,etc.were optimized.Experimental results indicated that digestion of arsenic in the alkaline solution is almost complete,the sulfur yield of 65%～75% is achieved.A new scheme for processing of arsenic cake from arsenic sulfide ore is suggested.%西藏昌都高纯硫化砷矿采用碱溶、常压低温氧化的工艺进行了试验研究。选取了符合当地实际的氧化剂，确定了氧化时间、氧化温度、催化剂用量等技术参数，结果表明砷在碱中溶解几近完全，硫磺产率可达65%～75%，为硫化砷矿和滤饼的加工，提供了新的方案。
