Microbially induced mineral beneficiation involves three strategies, namely, selective bioleaching of the undesirable mineral from an ore or concentrate, selective flotation of the mineral, or selective dispersion/flocculation. Such microbially induced beneficiation will find applications in a number of areas such as: Desulfurization of coals

Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other. No chemical changes to the minerals are made at this point in the mining process. The phosphate ore, or “matrix” as it is called locally, contains three different mineral groups which have to be separated from each other.
