摘　　要：根据火法炼铅锑弃渣的特点,对回转窑火法还原挥发富集该渣中的铟及其他有价金属进行热力学分析。计算出的渣中相关化合物最低还原温度及蒸气压与温度的关系表明了工艺的可行性,结果可为实际生产提供指导。The pyrometallurgical process of indium and other valuable metals enrichment from lead and antimony smelting slag by reduction-volatilization in rotary kiln is thermodynamically analyzed according to the slag characteristics. The technology feasibility is indicated by the lowest temperature of reducing compounds in slag and relationship of temperature and vapor pressure derived from the thermodynamic calculation, and the results will offer instruction for practical production.
