一、前言炼铅的主要原料为硫化铅精矿,矿物主要为方铅矿。世界上目前生产铅主要采用火法。将铅精矿先在烧结机上进行焙烧烧结,烧结块送鼓风炉熔炼,产出粗铅。粗铅再经火法或火法加电解进行精炼得精铅产品。这个过程效率比较高,能适应不同的原料,消 I. Introduction The main raw material for lead smelting is lead sulfide concentrate, and the mineral is mainly galena. The current lead production in the world mainly uses fire method. The first lead concentrate in the sintering machine roasting sintering, sinter blast furnace to send smelting, crude lead output. The crude lead is then refined by the fire method or fire method plus electrolysis to obtain refined lead products. This process is relatively efficient, can adapt to different raw materials, consumption
