粗锡精炼除铅,我国生产上多采用结晶法,产出纯锡和焊锡(Sn～65%、Pb～35%),焊锡再用氯化物电解液电解得精锡和阳极泥(氯化铅),再将氯化铅处理成粗铅。粗铅精炼除锡,一般是采用氧化法使锡氧化进入渣中,再用重选将氧化锡富集,然后炼成焊锡。
Crude tin refining lead removal, China’s production more use of crystallization, the output of pure tin and solder (Sn ~ 65%, Pb ~ 35%), and then the electrolysis of the chloride electrolyte electrolytic fine tin and anode slime (lead chloride ), Then lead chloride into crude lead. In addition to the crude lead refining tin, the oxidation method is generally used to make tin oxide into the slag, and then re-election will enrich the tin oxide, and then into the solder.
