Bioleaching review part B: SpringerLink

2003-10-18  Bioleaching of “dirty” concentrates, with their high smelter penalty costs, represents some of the most attractive new applications for stirred reactor bioleaching. In addition to stirred reactors, bioleaching of copper from chalcopyrite ore in heaps using thermophiles will likely become a reality within the next few years.
