• Kinetic models for the extraction of copper by Acorga

    2020-5-21 · In the present work the extraction kinetics of copper using the resulting actual leach solution obtained from the leaching of malachite ore in perchloric acid solutions and the stripping kinetics of copper from the loaded organic phase were examined. The organic phase was prepared by using Acorga M5640 and kerosene. In the extraction process the effects of the initial pH of aqueous solution

    While bulk extraction typically requires a two-step mixer-settler stage μSX precludes the need of a settler. A copper solution was produced by using sulfuric acid as leachant of a composite malachite–chalcopyrite ore. A microfluidic Y-Y channel placed on the format of a microscopy polymethylmethacrylate (PMMA) slide was used for the μSX
