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 processing.
