简单分析了“烧结-鼓风炉熔炼-吹炼法”处理脆硫铅锑矿存在的问题,并对真空冶金法处理脆硫铅锑精矿铅、锑、铁挥发控制条件进行了实验研究,研究结果表明:在蒸馏温度为1523 K、蒸馏时间为60 min的条件下,脆硫铅锑精矿的挥发百分含量约为77%;精矿中铅、锑的挥发百分含量在99%以上;精矿中铁基本不挥发,富集于残留物中;残留物主要物相为FeS。 The problems existing in the treatment of jasite from the “sinter - blast furnace smelting - blowing method” were analyzed briefly. The experimental conditions of the volatilization control of lead, antimony and iron from the crushed sulfur, lead and antimony concentrate by vacuum metallurgy were studied. The results showed that the volatilization percentage of jasite was about 77% at the distillation temperature of 1523 K and the distillation time of 60 min. The volatile percentage of lead and antimony in the concentrate was 99% Above; concentrate iron in the basic non-volatile, enriched in the residue; the main phase of the residue is FeS.
