介绍了株洲冶炼集团铅浮渣反射炉烟尘的特点及其中铟的分布 ,研究了硫酸直接浸出 萃取法从铅浮渣反射炉烟尘中提取铟的新工艺 ,研究证明在 2 0 0g·L- 1 硫酸溶液中浸出 ,铟的浸出率为 90 % ;用P2 0 4作萃取剂 ,适当条件下溶液中铟的萃取率可达 95 % ;用HCl作反萃剂 ,反萃率在 95 %以上。还研究了萃取剂的再生、铟的置换与熔铸以及萃余液的处理等生产工艺。 Introduced Zhuzhou Smelter Group lead scum refuse furnace dust characteristics and distribution of indium, the direct extraction of sulfuric acid from the lead scum refuse furnace soot extraction of indium new technology studies have shown that in 200g · L-1 Sulfuric acid leaching, indium leaching rate of 90%; P2 0 4 as an extractant, under appropriate conditions indium extraction rate of up to 95%; with HCl as stripping agent, stripping rate of 95% or more. Also studied the regeneration of extractant, indium replacement and casting and raffinate processing and other production processes.
