Bioleaching: metal solubilization by microorganisms | .
Abstract Bioleaching is a simple and effective technology for metal extraction from lowgrade 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. ...

Minerals | Topical Collection : Bioleaching
Bioleaching experiments showed that copper extraction from chalcopyrite bioleaching by both cultures was promoted significantly by Ag +, with more serious corrosion occurring on the minerals surface. SRXRD and XANES analyses showed that the intermediates S 0, jarosite and secondary minerals (bornite, chalcocite and covellite) formed for all bioleaching experiments.
