Bio beneficiation of iron ore by fungi

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

    Oct 01, 2006 Bolani iron ore slime containing 53% Fe, 9.56% Al 2 O 3 and 6.14% SiO 2 was subjected to bio-beneficiation studies. In situ leaching by A. niger removed about 38% of alumina in 15 days, while B. circulans could removed 39% of alumina after six days at 10% pulp density. Culture filtrate leaching with A. niger removed 20% alumina with 13 day
