Methods of Metal Recovery by Microorganisms (2 Methods)

Soil microorganisms are very closely involved as catalytic agents in many geological processes. These include mineral formation, mineral degradation, sedimentation and geochemical cycling. In recent years, a new discipline of mineral science namely bio-hydrometallurgy or microbial mining (mining with microbes) is rapidly growing.

Microbial Mining - SERC

Rio Tinto: The Rio Tinto is an extremely acidic river in southern Spain. Enduring over 5000 years of mining activity, the river is full of heavy metals. Surprisingly, phylogenetic studies show the diversity of eukaryotes to be much greater than that of prokaryotes. For more information about Microbial Mining, search the Microbial Life collection.

Mining and metallurgy: The role of filters in mining and ...

The 'mineral dressing' industry (i.e. the concentration of valuable ore materials out of its unavoidable mix with unwanted solids) is a good example of the employment of a very wide range of separation equipment, for use once the mined material has been comminuted to the state where the individual particles are each largely composed of one or ...

Bioleaching: metal solubilization by microorganisms | FEMS ...

Abstract. Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates.Non-sulfide ores and minerals can be treated by ...
