Bioleaching of copper ore flotation concentrates

These results have demonstrated that the bioleaching of Polish copper ore flotation concentrates can be realised in a special bioreactor (biorotor). Copper recovery was satisfactory (86% after 13 days treatment). The high copper extraction was achieved in the presence of iron ions (2 K medium) or pyrite (3%). The changes in the surface area of
