Beneficiation of iron ore by aspergillus only

Feb 05, 2021

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

    Aug 01, 2020 The beneficiation of iron ore is relatively more effective, when RAF operation applied along with magnetic concentration. Data indicate that it enhance the Fe% value from 29% of Fe to 50 % Fe. The magnetic operation removes the slimes, which beneficiate the iron ore of 65.22% of Fe whereas recovery percentage has been calculated 78.42% (Zhu
