中文摘要: 采用旋转管式炉对锡阳极泥进行焙烧，考察氧化气氛、还原气氛和硫化还原气氛三种焙烧方式对锡阳极泥中锑挥发率的影响。结果表明，在硫化还原气氛中，配入30%黄铁矿和10%焦粉量，1 000 ℃焙烧2 h时，锡阳极泥中锑的挥发率达到74.56%。硫化挥发的锡锑分离效果优于氧化挥发和还原挥发，与理论分析一致。
Abstract:Tin anode mud was roasted in rotary tube furnace. The effects of roasting in oxidizing atmosphere, reduction atmosphere, and vulcanization-oxidizing atmosphere respectively on antimony volatilization rate were investigated. The results show that the antimony volatilization rate is 74.56% under the conditions including pyrite dosage of 30%, dosage of coke powder of 10%, and roasting in vulcanization-oxidizing at 1 050 ℃ for two hours. The volatilization separation effect of tin and antimony in vulcanization atmosphere is better than that in oxidizing atmosphere and reduction atmosphere. The results are in accordance with the theoretical analysis.
