Microbial Leaching (Bioleaching, Biomining

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

Examples of Leaching Microbiology

2. Uranium Leaching: This is an indirect process in which the microbes do not interact with uranium ore directly but act on iron oxidant. Ferric sulphate and sulphuric acid can be obtained by Thiobacillus ferrooxidans from the pyrite within the uranium ore. The reaction is given below: 2FeS 2 + H 2 O + 7.5O 2 → Fe 2 (SO 4) 3 + H 2 SO 4

The dissolution of uranium in column under chemical leaching conditions (control experiment) recorded a lower value of 39%. To test the efficacy of L. ferrooxidans, column was operated under similar conditions resulting in uranium biorecovery of 66%. The acid consumption using A.ferrooxidans and L.ferrooxidans was estimated to be 3.2 and 2.8kg/T ore; as against 5.4kg/T in control experiments.

A comparison of the uranium recovery from low-grade ore by

Uranium can be released from sulfide minerals by direct and indirect bioleaching (Bosecker, 1997). In direct bioleaching, there is physical contact between the bacterial cell and the mineral sulfide surface. In indirect mechanism, the microorganisms need not be in direct contact with ore surface. In bacterial leaching of uranium ores, the

Biomining Wikipedia

Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining). These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons.
