Reductive biomining of pyrite by methanogens
Trends in Microbiology, 2022Pyrite (FeS2) is the most abundant iron sulfide mineral in Earth's crust. Until recently, FeS2 has been considered a sink for iron (Fe) and sulfur (S) at low temperature in the absence of oxygen or oxidative weathering, making these elements unavailable to biology. However, anaerobic methanogens can transfer electrons extracellularly to reduce FeS2 via

Genomics, metagenomics and proteomics in biomining microorganisms
Biotechnology Advances, 2006 The use of acidophilic, chemolithotrophic microorganisms capable of oxidizing iron and sulfur in industrial processes to recover metals from minerals containing copper, gold and uranium is a well established biotechnology with distinctive advantages over traditional mining.

Universal reserves of high-grade ores are diminishing at an alarming rate due to the rapid increase in the demand for metals. Biomining is the extraction of specific metals from their ores through biological means, usually microorganism. Biomining is done in two steps often called bioleaching and biooxidation.

Acidophilic microorganisms that oxidize mineral sulfides are of obvious biogeochemical significance in their natural habitats and are increasingly being utilized commercially in mineral sulfide processing. However, few studies have focused on their taxonomy and phylogeny, hence there are unresolved questions in these areas.

Biomining for mother nature's superlenses
2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017Conventional optical microscopes are restricted by a predetermined limit beyond which it is impossible to resolve distinct points in the objective field. The origin of this limited resolution is associated to the optical diffraction and the loss of evanescent waves in the far field. As a result, objects below this diffraction limit, such as subcellular

Biomining of Natural Resources
2017Biomining is the way towards removing significant metals from minerals and mine tailings with the help of micro-organisms. This process has emerged as an innovative biotechnological approach for extracting the essential metals from low-grade ores. Micro-organisms are utilized to filter out the minerals, instead of the ancient strategies including ...

The Biogeochemistry of Biomining
2010Biomining is a technology that harnesses the abilities of certain microorganisms to accelerate the dissolution of minerals, thereby facilitating the recovery of metals of value. In full-scale commercial operations, biomining currently mainly involves using consortia of acidophilic bacteria and archaea to bring about the oxidative dissolution of sulfide
