These natural capacities can be exploited for the bioremediation of mine impacted sites. Microorganisms also play a key role in phytostabilisation, either indirectly by promoting plant growth or directly through metals and metalloids mobilization or immobilization in soils. Thus, microorganisms are important actors of mining sites remediation.

In an era of environmental degradation, and water, and mineral scarcity, enhancing microbial function in sustainable mining has become a prerequisite for the future of the green economy. In recent years, the extensive use of rare earth elements (REEs) in green and smart technologies has led to an increase in the focus on recovery and separation
mining of gold and uranium by microorganisms. Mining With Microbes October 15 2012 Issue Vol 90 Issue 42 Oct 15 2012 Harnessing microbes to do mining work is called biomining for copper and gold Colorado based mining consultant Corale L Brierley estimates biomining as a way to harvest zinc nickel cobalt and uranium but many of
Abstract. A process for biological removal of iron from quartz sands, kaolins and clays was developed in which these industrial minerals were leached at 90°C with lixiviant produced as a result of the cultivation of acid-producing heterotrophic microorganisms, mainly strains of Aspergillus niger, at 30°C in a nutrient medium containing
26-9-2017· Researchers from the Department of Biology and Geoscience at the University of Akron, in the United States, say that communities of microorganisms play a role in the formation of unique iron ore caves, which make up only about one per cent of caves worldwide.
In modern mining industry several new processes are used which are easily applicable and economical and environment friendly. Application of biotechnology in mining industry to extract different metals is one of the above said new age techniques.
26-7-2018· Thermophilic microorganisms in biomining. In this scenario the use of thermophiles could be advantageous because higher operational temperature would increase the rate of the process and in addition it would eliminate the energy input for cooling the system Mining/methods*
For such ores, research is being done on the use of heterotrophic bacteria and fungi. In this case metals are dissolved by organic acids or complexing or chelating agents produced by the bacteria or fungi . Studies on silicate nickel ores have shown that nickel is dissolved by organic acids produced by microorganisms.

Mining industries produce vast waste streams that pose severe environmental pollution challenge. Conventional techniques of treatment are usually inefficient and unsustainable. Biological technique employing the use of microorganisms is a competitive alternative to
The outflow of acidic liquids and other pollutants from mines is often catalysed by acid-loving microorganisms; these are the acidophiles in acid mine drainage. Acidophiles are not just present in exotic environments such as Yellowstone National Park or deep-sea hydrothermal vents.
7-7-2013· Mining leaves an eyesore on the land. By ripping open mountains to extract the ores within, it sometimes leaves areas unusable after the mining companies have left. We can't go on this way, and politicians agree. It's why mining companies are working to reduce the environmental impact of mining
