摘要

Procedure to benefit tin ores, with separation and joint selection of valuable rare metals, consisting essentially of initially submitting minerals containing tin mainly, and those minerals or concentrates containing niobium, tantalum, thallium, titalium, tungsten, germanium as impurities and similar rare metals, to a fusion with a reducing element, by casting the impure metal obtained in appropriate molds, to give it the form of electrolysis anodes, which are taken to the corresponding baths, in which this electrolysis is carried out in a selective electrolyte, the tin depositing on the cathode and retaining the valuable elements contained in that impure metal in the form of anodic slimes, while remaining in the electrolyte dissolve those other metals that, even though they are soluble in it have less tendency to deposit in the cathode for its different, precipitation potential, the operation being completed by the separation and fusion of the tin deposited in the cathodes and the conventional purification of the rare metal groups.
