Recovery and Purification of Tin from Tailings from the Penouta Sn–Ta–Nb Deposit

Recovery and Purification of Tin from Tailings from the Penouta Sn–Ta–Nb Deposit

A concentrate obtained from mining tailings containing mainly cassiterite and columbotantalite was reduced for the production of tin metal. The compounds CaCO3, Na2CO3, K2CO3, and borax were used as fluxes in the pyrometallurgical reduction smelting process, and graphite was employed as the reducing...
