BENEFICIATION, DEPHOSPHORIZATION AND

Apr 30, 2012  Unfortunately, this large reserve cannot be utilized for the production of pig iron due to its high sulphur and phosphorus contents. In addition, the ore cannot be beneficiated easily like Itakpe and Oshokoshoko iron ores because of its texture. This work studied the beneficiation, dephosphorization and desulphurization of Agbaja iron ore.

Ore Beneficiation - an overview ScienceDirect Topics

Microbially induced iron ore formation has been confirmed at Gunma iron ore mine, Japan [21]. 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 ...

Jan 01, 2019  However, Jaruwa iron ore contains higher iron content (68%) than Agabja iron ore (53%). The SiO2 (13%) and Al2O3 (7%) of Jaruwa iron ore are also lower than Agbaja iron ore; SiO2 (17%) and Al2O3 (20%). This is an indication that Jaruwa iron ore will be preferred to Agbaja iron ore for the production of pig iron or direct reduced iron.
