    Primary copper sulfides are recalcitrant to bioleaching, probably due to semi conductivity or passivation effects which result in slow dissolution kinetics. The mineral dissolution strongly depends on redox reactions and, consequently, electrochemical techniques are recommendable for analyzing and processing of redox active minerals. For this reason we installed a three electrode system into a
