Lead-tin Recovery Project
The lead-tin recovery project is design to extract the tin metal from the lead-tin alloy(Pb-Sn Alloy) or lead-tin-antimony alloy(Pb-Sn-Sb alloy), which are the slag from the crude lead refining or lead acid battery recovery. The lead-tin-antimony is the core metallurgy equipment of the project.
