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

Thermophilic microorganisms in biomining
World Journal of Microbiology and Biotechnology, 2016Biomining is an applied biotechnology for mineral processing and metal extraction from ores and concentrates. This alternative technology for recovering metals involves the hydrometallurgical processes known as bioleaching and biooxidation where the metal is directly solubilized or released from the matrix for further solubilization, respectively ...

Streptomyces rock phosphate ore biomining evaluation in vitro
Journal of Environmental Radioactivity, 2023The process of extracting metals from rock phosphate ore (RPO) by using microorganisms to convert them into soluble compounds is called biomining. Phosphorus is one of the elements proposed to be extracted from RPO. To understand the role of Streptomyces phospholyticus, 12 isolates of Streptomyces were isolated from RPO, their ability to grow on ...

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 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 ...

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

Ore bodies buried deep in Earth's crust could meet increasing global demands for metals, but mining them would be costly and could damage the environment. Reinventing an ancient technology for bioleaching metals could provide a solution.

Nucleic Aacid Extraction from Biomining Microorganisms
Advanced Materials Research, 2009Various methods of nucleic acid (NA) extraction were investigated with the aim of developing a quantitative method of NA extraction from five representative strains of biomining microorganisms. The process of removing cells from mineral surfaces, lysing microorganisms, precipitating NA and purifying RNA were analysed.
