Volatilization of Tin Chlorides. More than 95 percent of the total tin in Bolivian mine-run ores can be volatilized and recovered as tin chlorides at temperatures ranging from 520° to 565° C. Equally high percentage recoveries of tin can be obtained from low-grade Bolivian concentrates at temperatures of 565° to 600° C. Minus 35-mesh ores

Hydrometallurgy refers to the application of aqueous solutions for metal recovery from ores, and has been practiced for copper recovery for many years. The original impetus for solution methods for copper extraction before the development of froth flotation technology was the existence of large ore bodies of low copper content which were uneconomic to work using conventional smelting methods.

The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum. The ore is then concentrated at or near the mine site, to increase the weight of tantalum oxide and niobium after which the material is concentrated through wet gravity techniques along with electrostatic and electromagnetic processes.
