Leaching of chalcopyrite concentrate by hydrogen peroxide in sulphuric acid solution
Due to complex mineralogy and/or low content of base metals, some ores and mineral concentrates are not suitable for pyrometallurgical treatment. Therefore, those ores and concentrates have to be treated by application of the hydrometallurgical processes. Lower energy consumption and lower environmental impact are important advantages of hydrometallurgy over pyrometallurgy. Leaching of sulphide minerals requires presence of oxidants in acidic environment. Influence of temperature on leaching degree of copper from chalcopyrite in presence of hydrogen peroxide under atmospheric pressure was investigated in this paper. Results of the chemical and X-ray diffraction analysis of the concentrate and leaching residue were used in order to explain mechanism of the copper leaching from the mineral concentrate.
