    Hydrometallurgical Process - an overview

    Pyrometallurgical processes resulted in the formation of approximately 3.4 t of SO 2 for every 1 t of copper. The hydrometallurgical process included pressure leaching under slightly oxidising conditions in diluted sulphuric acid (at 80–105 C and 140-350 kPa oxygen pressure). This enabled selective extraction of up to 97% of copper, with less than 10% of pyrite taking part
