摘要: Galvanic interaction between particulate chalcopyrite (CuFeS2) and copper results in the rapid conversion of to chalcocite. The effects temperature, surface area, concentration sulfuric acid agitation were systematically evaluated. kinetics found be controlled by a steady-state current flow effective anodic cathodic areas involved galvanic couple. experimental activation energy was 11.5 stoichiometric data reaction products have been characterized. overall kinetic system has evaluated based upon an electrochemical model.
