<p>Process for the benificiation of ores, comprising the dissolution of pyrite, pyrrhotite or other gangue reduced iron and/or sulfur compounds by a strain of Thiobacillus ferrooxidans capable of oxidising iron and sulfur. The valuable metal is not solubilised by the micro-organism. The process is especially applicable to the treatment of tin ores, before, during or after beneficiation and also tailings from tin beneficiation which can contain up to 14 % of the tin originally present in the ore.</p> |
