2018-11-1 It has been demonstrated that ore agglomerated in extreme condition with high concentrations of acid and chloride ions and cured for long periods enhances the dissolution rate of a chalcopyrite ore. In these conditions, pH values remain low due to an increase in proton activity in the presence of chloride ions. •
