APPLICATION OF MICROBIAL OXIDATION OF PYRITE

Thiobacillus f errooxidans can be self-cultured in the acidic mine water after nourishing treatment.The mine water containing Thiobacillus ferrooxidans has been used in the heap leaching of pyritic-coal-bearing kaolin ore. The kaolin ore has been purified through the oxidation leaching of pyrite to remove the sulfur and iron impurities.
