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.
