Iron ore is an important raw material for steel production enterprises. In most cases, iron ore with a grade of less than 50% requires ore beneficiation before smelting and utilization. Natural ore (iron ore) is gradually selected for iron through procedures such as crushing, grinding, magnetic separation, flotation, and gravity …
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.
