Extraction of copper from complex carbonaceous sulfide

2021-11-1  A gradual increase in copper extraction was noted when the temperature was increased from 100 to 160 °C, during which a temperature increase of 20 °C, accordingly yielded an increase of about 20% in copper extraction. However, a further increase in temperature to 180 °C, did not yield a significant improvement in copper dissolution.
