硫酸铜生产工艺流程的优化设计

Optimization Design of Production Technology for Copper Sulfate

研究探讨硫渣隔膜电解、回转窑氧化还原焙烧、含铜焙砂硫酸浸出、浸出液冷却结晶生产硫酸铜,浸出渣再经回转窑氧化还原焙烧产出合格含锡焙砂,供给锡熔炼系统作为二次原料使用的优化工艺设计方案。

Research and probe on the optimization process design scheme of which through sulphur slag cha- phragm- electrolyzing, rotary redox roasting, the copper -bearing calcine being leached by sulfuric acid, and the leaching solution cooling and crystallizing, the copper sulfate can be produced, and then when the leaching residue was again redox roasted by rotary kiln, the qulified tin - bearing calcine can be formed which can be used as secondary raw material for tin smelting system.
