    Feasible bioprocessing technologies for low-grade iron

    01/05/2015· With increasing demand for steel and depletion of high-grade iron ore deposits, more research efforts are being directed toward extending the life of existing ore reserves and developing technology to treat low-grade iron ore resources. Among all the reported technologies, biotechnologies in mineral processing — specifically bioleaching and microbially induced flotation — have emerged to

    Bio-Beneficiation of Australian Iron Ores Potential

    Iron ore currently mined in Australia generally requires very little beneficiation. However, depleting high-grade resources means that in the future low-grade iron ore deposits will need to be mined to meet the increasing demands of the global steel industry. Along with the increased demand, the industry faces additional pressure to reduce the environmental impact of mining and mineral

    The bioflotation technique is in the fundamental stage, and considerable research is still necessary before its industrial application. A fundamental bioflotation study should determine the response of each mineral that is present in an ore. Thus, considering that phosphate ores are associated with several gangue minerals, especially quartz, carbonates and silicates, then a detailed
