Ore Beneficiation - an overview | ScienceDirect Topics

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

Jan 08, 2016 An alternative technique for the beneficiation of these ores is the calcination. Calcination is the process of heating the ore to a high temperature ranging from 800 to 1000 C to decompose CaCO 3 and MgCO 3 to CaO, MgO and gaseous CO 2. The CaO and MgO formed are then removed as hydroxides by quenching the calcined product in water and washing
