Mining with Microbes Nature Biotechnology
Microbes are playing increasingly important roles in commercial mining operations, where they are being used in the “bioleaching” of copper, uranium, and gold This discovery lead to the development of complex modern biomining systems Biomining is the use of microorganisms to leach metals from their growth medium These systems can be used for bioremediation, Biomining
ScienceDirect From exploration to remediation: A
Finally, microorganisms may be used in a number of strategies for mine remediation; specifically, we review in detail microbially accelerated carbon capture and In this review, we examine the microbial dissolution of arsenicbearing minerals as a side effect of biomining processes, with special emphasis on (1) the Arsenictransforming microbes and their role in
Microorganisms and their application in mining and allied
Antioxidant defenses against ROS in microbial cells and the use of ROS by antimicrobial host defense systems are covered and reactive nitrogen species and Thus microorganisms may help to regenerate the iodide–iodine lixiviant by oxidising I − to I 2, and on the other hand, contribute to the loss of the lixiviant through volatilisation, accumulation and sorption Some microorganisms can also reduce iodate (IO 3−) to I − (for a review, see Amachi, 2008 )The role of microorganisms in gold processing and recovery—A review
Biomining: metal recovery from ores with microorganisms
Bioleaching is a conversion of an insoluble valuable metal into a soluble form by means of microorganisms In biooxidation, on the other hand, gold is predominantly unlocked from refractory ores in largescale stirredtank biooxidation arrangements for further processing steps In addition to copper and gold production, biomining is also usedInsitu leaching technology is now widely used to exploit ion adsorption rare earth ore, which has caused serious environmental problems and deterioration of mining soil ecosystems However, our knowledge about the influences of mining operation on the microbiota in these ecosystems is currently very limited In this study, diversity Microbial communities in rare earth mining soil after

Biotechnology for the extractive metals industries SpringerLink
Abstract Biotechnology is an alternative process for the extraction of metals, the beneficiation of ores, and the recovery of metals from aqueous systems Currently, microbialbased processes are used for leaching copper and uranium, enhancing the recovery of gold from refractory ores, and treating industrial wastewater to recover metal 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 in Role of microorganisms in bioleaching of rare earth elements

Thus, microorganisms are important actors of mining sites remediation Advances in the field of high throughput sequencing techniques have revolutionized molecular biology and opened a new era in research on microbial ecology,enabling to explore the diversity and activity of microbial communities thriving in polluted environmentsBiological processing method microorganisms have an important role in 1 the processing of lowgrade goldbearing ores (mining waste and tailings) using bioleaching for direct gold extraction, asThe role of microorganisms in gold processing and
Biomining
Biomining is the use of microorganisms to leach metals from their growth medium These systems can be used for bioremediation, biohydrometallurgy, or even extracting metals from ores for commercial use It was later discovered that some fungi also leach metals from their environment [3]The use of microorganisms to facilitate the extraction and recovery of precious and base metals from primary ores and concentrates, Biomining is used by the mining industry to extract copper, uranium, and gold from lowgrade ores but not for lowgrade manganese ore in industrial scaleBioleaching and Biomining SpringerLink
Bacterial communities in mining soils and surrounding areas
Mining activity is causing environmental change in the landscape, particularly by changing the vegetation cover and affecting soil and water from the mine boundary region 2 Furthermore, the mining activities require an additional area to be used for disposal of waste, and years of intensification affect the quality of surrounding soils Role of Microorganisms in Mining: Generation of Acid Rock Drainage and its Mitigation and Treatment N Kuyucak* Golder Associates Ltd, 1796 Courtwood Cr, Ottawa, ON K2C 2B5, Canada Received 2 May 2002 accepted 4 October 2002 ABSTRACT Natural oxidation of sulphide mineral wastes during their disposal and storage at the mining sites mayReview Role of Microorganisms in Mining: Generation of Acid
White biotechnology and the production of bioproducts
White biotechnology uses enzymes and microorganisms to produce valueadded chemicals from renewable sources White biotechnology provides valuable components for the food, pharmaceutical, agricultural sectors as well as other industries Metabolic diversity in fungi, yeast, and bacteria can be exploited to produce food Bioleaching is a technique in biomining, which uses microorganisms to solubilise your metal(s) of interest [1] Therefore, you can see that the difference lies in what happens to your metal(s) of interest If your metal of interest is to be dissolved in solution by microorganisms, then the correct term to use is ‘bioleaching’Biomining of Gold European Training Network for the
Biosorption of heavy metals by microorganisms: Evaluation of
Various microorganisms such as bacteria, fungi, and algae were used to clean heavy metal contaminated environments, with more chemisorption sites in the form of immobilizations that could adsorb heavy metals, using single, consortia, and immobilized forms of metal resistant strains to repair heavy metalsIn order to enhance the effectiveness of phytoremediation processes in mine tailing and other heavily polluted environments, several studies have been conducted on supporting technologies such as use of microorganisms that promotes plant growth and assessment of the feasibility of microorganisms in assisting phytorestoration of mines Role of microorganism in phytoremediation of mine spoiled soils
Microbiological Oxidations of Minerals in Mine Tailings
Abstract Industrially significant metal sulfides are relatively stable in their natural crystalline form As a result of mining activities, these minerals are exposed and interact with water, oxygen, carbon dioxide, and soluble chemical species, factors which collectively enhance the mineral dissolution The very nature of mining practicesBacterial mining (biomining) represents the use of microorganisms to leach out metals from ores or mine tailings (wastes), followed by the subsequent recovery of metals of interest from the leaching solution This leaching of metals from ores is a natural process, which can be considerably accelerated by inducing and/or supporting the Bacterial Mining: Petroleum Science and Technology: Vol 25, No 11
