Ore Beneficiation

Ubiquitous microorganisms inhabiting iron ore deposits are useful in iron ore beneficiation (e.g., removal of alkalis, silica, clays, phosphorous, and alumina). Because the presence of phosphorous in the iron ore promotes bacterial growth (as an energy source), iron oxide particles having higher phosphorous contents were seen to be colonized by different bacterial cells.

Metallurgy

This method is employed in case where the ore is to be in a very pureform, e.g., aluminium extraction. Bauxite (Al 2 O 3 ), an ore of aluminium, contains SiO 2 and Fe 2 O 3 as impurities. When bauxite ore is treated with NaOH, the Al 2 O 3 goes into solution as sodium meta-aluminate leaving behind the undissolved impurities [Fe 2 O 3, SiO 2, Fe(OH) 3,etc.], which are then filtered off.
