Recent advances in microbial mining SpringerLink

1996-9-1  Microbial mining of copper sulphide ores, has been practiced on an industrial scale since the late 1950s. Since then, advances in microbial mining and the role of microorganisms involved in solubilization of metals have assumed commerical importance. The fact that bioleaching processes save energy, have a minimum pollution potential and are able to yield value-added by-products make these ...

Microbial communities in rare earth mining soil after

2021-2-10  Because of in-situ leaching mining, large amounts of REEs and ammonium are accumulated in mining soils. Microbial communities and essential biogeochemical processes are disrupted, and microbial populations and their dynamics associated with leaching solution and REEs should be shifted/reshaped (either enhanced or inhibited).

In Situ Leaching – Microbial Mining

In situ leaching is the process of performing leaching inside the mine itself and is usually done inside abandoned or disused mines. When mines are made, there must be a support structure left behind to stop cave-ins. In some mines this is sometimes done by leaving pillars of stone standing, these pillars containing metal ores.

Biomining: metal recovery from ores with

Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.
