Hydrometallurgical Copper Extraction Process

The successful development of the Cyprus Copper Process has been an evolutionary series of events covering a time span of some seven years. What does the Cyprus Copper Process do? Very simply, it converts copper concentrates of varying composition into copper metal which has been proven to be equivalent in every way to electrolytic tough pitch copper suitable for electrical applications. This

Hydrometallurgical Processing 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 in the reaction.
