摘　　要：利用Fact Sage6.2软件进行热力学计算,绘制不同温度Sb-S-O系热力学平衡图。采用单因素试验法对辉锑矿富氧挥发熔池熔炼工艺进行研究。考察了反应温度、富氧浓度及反应时间对辉锑矿富氧挥发熔炼渣锑含量的影响规律,获得优化工艺参数为:反应温度1200℃,反应时间60 min,富氧浓度80%。优化试验条件下辉锑矿富氧挥发熔炼渣含锑低至0.33%。The Pourbaix diagrams of Sb-S-O system were drawn by thermodynamic calculations using the soft- ware FactSage6.2. Effects of reaction temperature,oxygen-enriched concentration and reaction time on oxygen-en- riched volatile bath smelting of stibnite concentrate were investigated. The optimum condition is determined as fol- lows：reaction temperature 1200 ℃ ,reaction time 60 min and oxygen-enriched concentration 80%. Under above- mentioned conditions,the content of antimony in slag is as low as 0.33%.
