中文摘要：
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。
英文摘要：
Here,we experimentally addressed the extraction of Pb and Sb from jamesoniteconcentrate by vacuum distillation.The influence of the distillation conditions,including but not limited to the distillation temperature,distillation time and pressure,on the removal of Pb and Sb was investigated with X-ray diffraction,titrametric analysis and atomic absorption spectrometry（AAS）.The preliminary results show that depending strongly on the distillation temperature and time,vacuum distillation is capable of removing most Pb and Sb from jamesonite in a simple and environmental friendly way.To be specific,distilled at 1523 K for 60 min.over 99%of both Pb and Sb were removed from the jamesonite,and most Fe stayed in the slag,existing in FeS-phase,because of poor volatilization of Fe.
