摘要: In the present work, extraction kinetics of copper using resulting actual leach solution obtained from leaching malachite ore in perchloric acid solutions and stripping loaded organic phase were examined. The was prepared by Acorga M5640 kerosene. process, effects initial pH aqueous solution, concentration copper, extractant concentration, temperature, stirring speed on rate investigated. acid, speed, It determined that increased with increasing decreasing ions. it observed temperature concentration. both solvent processes could be described first order pseudo homogenous reaction model. activation energy for calculated to 50.04 kJ/mol 32.42 kJ/mol, respectively.
