A variety of microorganisms can catalyze the solubilization of minerals in natural environments. Besides Thiobacillus ferrooxidans, which can extract metal from metal sulfides, several other microorganisms such as silicate bacteria Bacillus mucilaginosus and fungi Aspergillus niger have been found to be progress in mineral bioleaching. Bacillus mucilaginosus can dissolve silicate from silicate minerals, and Aspergillus niger can dissolve metal from oxidative minerals. In this study, three types of microorga...
