Biobeneficiation of Iron Ores

Jan 02, 2012· Several microorganisms which are present ubiquitously in many iron ore deposits act as reagents, collectors or modifiers, to bring about selective mineral separation. Microbially-induced beneficiation of iron ores is a new concept having potential industrial applications in iron ore mining industries, worldwide.

Aug 08, 2017· In order to ensure iron concentrate grade and iron recovery, a large number of processing reagents are selected and applied in the iron ore beneficiation. The process water carried plenty of residual processing reagents, and such wastewater with color depth and strong smell could seriously affect the environment and the local people.
