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 ...

Biobeneficiation of Iron Ores - sapub

Jan 02, 2012  Utilization of aerobic and anaerobic microorganisms in iron ore beneficiation is discussed. Microorganisms such as Paenibacillus polymyxa, Bacillus subtilis, Saccharomyces cerevisiae (yeast) and Desulfovibrio desulfuricans (SRB) are capable of significantly altering the surface chemical behavior of iron ore minerals such as hematite, corundum, calcite, quartz and apatite.

Iron Ore Beneficiation SRK News

However, for other iron ore types, full liberation of the iron minerals may not be required. Direct Shipping Ores, as the name suggests, require no beneficiation, although frequently wet screening is required, (particularly for tropical deposits), to minimise adhesion of fines to a potential Lump product.
