一前言降低铅精矿中砷的含量是一个复杂的课题,也是当前的一些选矿厂急待解决的一个问题。对一些矿山铅精矿含砷调查的结果表明,毒砂的混入是造成铅精矿含砷高的本根原因。因此,研究毒砂与方铅矿的分离对降低铅精矿含砷具有重要意义。目前国内外对毒砂与方铅矿分选的实践尚不多见。从广东处理含砷铅锌硫化的浮选实践
Preface Reducing the arsenic content of lead concentrates is a complex issue that is also a pressing issue for some current concentrators. The results of the survey of arsenic in some mine lead concentrates show that the incorporation of arsenopyrite is the root cause of high arsenic in lead concentrates. Therefore, the study of the separation of arsenopyrite and galena is of great importance to reduce arsenic in lead concentrate. At present, the practice of arsenopyrite and galena separation at home and abroad is still rare. Flotation Practice of Treating Arsenic Lead and Zinc from Vulcanization in
