Industrial study on separation of tin from crude lead in reverberatory furnace
When copper dross is treated in the reverberatory furnace in lead smelting,tin mainly enters into crude lead and copper matte,and then into electrolytic lead and electrolytic copper respectively,at the same time lead to the loss of metal tin.In view of this situation,this paper studies the separation and recovery of tin from crude lead in reverberatory furnace on the basis of oxidation and slagging of copper scum according to the affinity of metal to oxygen element,it can effectively concentrate metal tin in slag phase during copper scum oxidation and slagging,and realize the enrichment and separation of metal tin,the refined tin can also be produced by further smelting,vac-uum distillation,electrolysis and so on,so as to realize the comprehensive utilization of valuable elements and im-prove enterprise benefits.
