However, there are still a lot of questions and uncertainties remained in future regarding bio-beneficiation of iron ore including: the complexity of microbial growth, reproducibility concern, lack of quantitative analysis and control methods, and the organic carbon requirement. Hence, future work is still required to address these above questions.

The pressure on the steel industry to reduce its carbon footprint has led to discussions to replace coke as the main reductant for iron ore and turn to natural gas, bio-syngas or hydrogen. Such a major transition from the blast furnace-basic oxygen furnace route, to the direct reduction-electric arc furnace route, for steel production would drastically increase the …

In past decades, preferences of international iron-ore trade markets have moved to lowphosphorus iron ores because of the well-known detrimental effects of phosphorus on steel and other iron-related materials, but little attention has been paid to biological dephosphorization orIron ores. In past decades, preferences of international iron-ore trade markets have moved …

Biobeneficiation to upgrade low-grade sulfide and iron ores has the potential to turn closed mines or uneconomic mineral deposits and secondary wastes and materials into economic resources. Microorganisms and their metabolites have been commercially applied in the bioleaching of metals from medium- and low-grade sulfide minerals for many years. Efforts are …

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 …

Iron ore is essential in steel making; however, high-grade ores have diminished, making low-grade ores inevitable. These low-grade iron ores need further beneficiation to upgrade the iron content. Currently, traditional physical and chemical methods are utilized and are not environmentally friendly. Bio-beneficiation techniques have emerged as a sustainable …

Bio-beneficiation of iron ore potentially offers a relatively energy-efficient, cost-effective, and environmentally friendly method of maximum iron ore recovery. However, this review has ...

Bio beneficiation involves the targeted elimination of unwanted minerals from an ore through the use of microorganisms, leading to the concentration of the desired mineral in ore Several microorganisms have been studied for the ability to keep aluminium unaffected and remove the iron content from ore without the loss of alumina.

The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and agglomerated pellets (Iron and …
