biohydrometallurgy

A branch of biotechnology which uses bacteria for industrial processes—e.g., microbial mining, oil recovery, bioleaching, water treatment, etc. It is used primarily to recover certain metals—gold, copper, zinc, lead—from sulphide ores.

In September, researchers from France and Germany reported the results of work recently undertaken on bioleaching copper from shale deposits in Europe, in a keynote paper to the 22nd International Biohydrometallurgy Symposium in Freiberg, Germany, the authors described how the laboratory-scale study had involved using leaching bacteria initially to convert insoluble ore minerals into water-soluble salts, with subsequent recovery of 97% of the contained copper by biochemical precipitation.
During the last 30 years bioleaching of minerals has opened up new opportunities for extractive metallurgy and biohydrometallurgy is now practiced in the copper industries, especially for the treatment of low-grade ores.
