一、前言 60年代以来,我国对西南各省丰富的脆硫锑铅矿资源的开发利用作了大量工作。其中锑铅精矿火法生产锑铅合金已经投产,但二氧化硫对环境的污染及锑铅分离问题至今尚未解决;湿法处理锑铅精矿尚处于试验阶段,存在的问题仍然是产品成份互相渗杂和回收率较低。
I. Introduction Since the 1960s, a great deal of work has been done in the development and utilization of the abundant jianjian lead mineral resources in the southwestern provinces. Among them, antimony and lead concentrate fire production of antimony and lead alloy has been put into operation, but the environmental pollution of sulfur dioxide and antimony and lead separation problem has not yet been resolved; wet processing of antimony and lead concentrate is still in the experimental phase, the existing problems are still the product ingredients mutual infiltration Miscellaneous and recovery rate is low.
