3.3 Mineral Beneficiation Waste. Mineral beneficiation is the first step after mining in the minerals and metal value chain. Mineral beneficiation consists of the manipulation of the physical properties of the ore to (1) produce desired particle sizes for a final product (2) liberate and concentrate the value mineral from the gangue material.

Beneficiation - an overview | ScienceDirect Topics

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 and oils.
