In this study, copper extraction from copper oxide ore using phosphoric acid solution as leaching agent was investigated, wherein the effects of the main factor temperature on the leaching of the copper oxide ore was researched, together with the leaching kinetics. It was experimentally demonstrated that the copper leaching rate increased with the increasing reaction temperature. Moreover, the leaching process can be described by the shrinking core model for surface chemical reaction. The activation energy of the leaching process was determined to be 30.65kJ/mol..

Keywords:Copper oxide ore;phosphoric acid; temperature; kinetics
