Copper chloride leaching from chalcopyrite and bornite ...

Copper chloride leaching from chalcopyrite and bornite concentrates containing high levels of impurities and minor elements has been studied using a two-stage countercurrent leach circuit at 95 °C to maintain a high copper extraction and a low cupric concentration in the pregnant leach solution for subsequent copper solvent extraction.

Experimental replacement of chalcopyrite by bornite ...

This suggests that the process is governed by diffusion of copper and iron through a sulphur framework. It is suggested that the observed formation of oriented bornite lamellae in chalcopyrite and in ISS during the chalcopyrite+chalcocite reaction may be explained by "replacement exsolution" at constant temperature.
