Biomining is the biotechnology that uses microorganisms to recover metals, in particular copper and gold, from ores and concentrates. Having developed from a very simple operational process, biomining has developed into a multi-faceted technology, to the extent that many of the largest industrial stirred tanks and heaps throughout the world are employed for biomining minerals Biomining [Douglas E. Rawlings, D. Barrie Johnson] on Amazon.com. *FREE* shipping on qualifying offers. Biomining uses microorganisms to recover metals, in particular copper and gold, from ores and concentrates. This book takes a strong applied approach to the study of biomining. It describes emerging and established industrial processes Biomining is applied bioleaching and biooxidation with the aim of extracting metals from ore in contrast to acid mine drainage which is uncontrolled and unintentional.. Questions . When is biomining economically viable? What advantages does biomining have over other metal extraction methods? Biomining is the extraction of specific metals from their ores through biological means usually bacteria. Although it is a new technique used by the mining industry to extract minerals such as copper, uranium and gold from their ores but now a days, biomining occupies an increasingly important place among the available A Green Technology to Mine Valuable Metals Biomining is the process of extracting valuable metals from ores and mine tailings with the assistance of microorganisms. It is an effective and Biomining: A Green Technology to Mine Valuable Metals- A Global Perspective Biomining is the use of microorganisms in the recovery of metals from ores. During bioleaching, metals such as copper, nickel or zinc are oxidized through microbial action from the water-insoluble sulfide to the soluble sulfate forms. Although gold is inert to microbial action, microbes can also be used in gold recovery from certain types of ores because as they oxidize the ore, they open up REFERENCES SITED [1] Rawling, D. E. "Biomining Theory, Microbes and Industrial Processes. " 1997 Springer-Verlag Berlin Heidelberg and Landes Bioscience Georgetown, TX, USA. Information on the theory of microbes and how it is applied to industrial processes. It also looks at various case studies of the application of biomining.

Moved Permanently. The document has moved here. Biomining is the generic term that describes the processing of metal-containing ores and concentrates using (micro-) biological technology. This is an area of biotechnology that has seen considerable growth in scale and application since the 1960s, when it was first used, in very basically engi- Biomining is the biotechnology that uses microorganisms to recover metals, in particular copper and gold, from ores and concentrates. Having developed from a very simple operational (in terms of both engineering and biology) process, biomining has developed into a multifaceted technology, to the extent that many of the largest industrial stirred tanks and heaps throughout the world are Biomining is the biotechnology that uses microorganisms to recover metals, in particular copper and gold, from ores and concentrates.
