Developments in Biotechnology for Environmentally Benign Iron Ore

Biobeneficiation of iron ores has potential industrial applications. In this paper, biotechnological aspects of environmentally benign iron ore beneficiation are illustrated with respect to biomineralisation, mining microorganisms, surface chemical aspects of microbe-mineral interactions and role of mineral-specific bioreagents.Mine-isolated microbes can therefore be used to bring about selective removal of iron, calcium or silica from the bauxite ores. In this paper, role of microorganisms in the biogenesis and biomineraliztion of bauxite deposits is analysed.

This study investigated a potential biological method that can be further developed for the full biobeneficiation of low-grade iron ore minerals. Twenty-three bacterial strains that belong to Proteobacteria, Firmicutes, Bacteroidetes and Actinobateria were isolated from the iron ore minerals and identified with sequence homology and phylogenetic methods.This study has demonstrated the utility and amenability of microbially-induced mineral beneficiation of iron ores through bacterial and yeast cells and their metabolic byproducts. Utilization of aerobic and anaerobic microorganisms in iron ore beneficiation is discussed.

22.4: Beneficiation Chemistry LibreTexts

Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away.In this review, current developments in the biobeneficiation of iron ore minerals are considered, and potential solutions to challenges faced in the wider adoption of this technology are proposed.(PDF) Getting rid of the unwanted: highlights of developments and

Technical Potential for Bioleaching and Biobeneficiation of Ores

The extraction of copper from sulfidic copper ores through the agency of acidophilic iron-oxidizing bacteria, e.g., Thiobacillus ferrooxidans, has become an industrially accepted technology in mining and mineral processing, especially for low-grade ore, and is now also receiving serious consideration for high-grade ores and ore concentrates (see chapters The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making.

Bio-Beneficiation of Australian Iron Ores Potential Applications

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 22. Mining Industry Profile: Iron In 1984, the iron ore industry used a total of 652 billion gallons of water, down from a high of 849 billion gallons in 1973. Of the total water usage in 1984, approximately 584 billion gallons (90 percent) were recirculated water; 68 billion gallons were from new water sources.Beneficiation ore PDF SlideShare
