Copper Oxide Ore Leaching Ability and Cementation

The cementation process of copper by iron powder is provided by following equation: Cu 2 + + Fe ⇒ Cu + Fe 2 +. As a result of the differences in electrochemical potentials, a reaction will take place. The reaction potential of Iron and Copper is presented in Table 3. (∆G˚) 298 = −20.29 − 15.54 = −35.83 Kcal.

Abstract: Mechanochemical sulfidization of a mixed sulfide/oxide copper ore by co-grinding with sulfur and additives including Mg(NO 3) 2 and Fe(NO 3) 3 salts and iron, aluminum and magnesium powders was investigated for the first time. Also, the influence of sulfidization during the wet-milling process was examined on the separation efficiency and recovery of copper in detail.
