Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from lowgrade ores is the most important industrial appliion and a significant part of world copper production already originates . Biomining: metal recovery from ores with microorganisms Adv Biochem Eng Biotechnol. .
Microbial mineralization (corrosion, decomposition, and weathering) has been investigated for its role in the extraction and recovery of metals from ores. Here we report our appliion of biomineralization for the microbial enhanced oil recovery in lowpermeability oil reservoirs. It aimed to revea .
Microbial leaching processes are currently used for the winning of gold and copper from lowgrade ores ('bioleaching'). Solid industrial waste materials such as fly ash, sludges, or dust might also be microbially treated to recover metals for the reuse in metalmanufacturing industries. Bioleaching allows the cycling of metals by a process close to natural biogeochemical cycles reducing ...
Microbial leaching is the process by which metals are dissolved from ore bearing rocks using microorganisms. For the last 10 centuries, microorganisms have assisted in the recovery of copper dissolved in drainage from water. Thus biomining has emerge as an important branch of biotechnology in recent years. Microbial technology renders helps in case of recovery of ores which cannot be ...
Target minerals activation pretreatment insides ore and other enhanced minerals exposing technology. Bioleaching process control, like weakened passivation methods, especially for copper sulfide bioleaching. Environmental Protection and Security. With the exposition of environmental contamination, increased focus has been placed on leakages and insecurity during the bioleaching .
Microbial enhanced oil recovery (MEOR) is a biological based technology consisting in manipulating function or structure, or both, of microbial environments existing in oil ultimate aim of MEOR is to improve the recovery of oil entrapped in porous media while increasing economic profits. MEOR is a tertiary oil extraction technology allowing the partial recovery of the commonly ...

Microbial enhanced oil recovery (MEOR) is on e of the EOR techniques where bacteria and their byproducts are utilized for oil mobilization in a reservoir. In principle, MEOR is a process that increases oil recovery through inoculation of microorganisms in a reservoir, aiming that bacteria and their byproducts cause some beneficial effects such as the formation of stable oilwater emulsions ...
· Microbial enhanced oil recovery (MEOR) is potentially useful to recover incremental oil from a reservoir being beyond primary and secondary recovery operations. Effort has been made to isolate and characterize natural biosurfactant produced by bacterial isolates collected from various oil fields of ONGC in Assam. Production of biosurfactant has been considered to be an effective major .
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 of REEs from ore matrices. However, the recovery ...
