Abstract
Malaco Copper Mine at Mengapor, Pahang is planning to treat their low grade copper ores using heap leaching technique. Unfortunately, the pregnant leach solution produced from this leaching is believed to contain impurities which is manganese, nickel, iron and zinc. Therefore, a simulation of this problem is developed by treating the synthetic copper(II), nickel(II) and manganese(II) aqueous solution with selected chelating ion exchange resin Amberlite IRC 748 which has iminodiacetic (IDA) functional group. The results showed that the maximum loading of copper(II) obtained is 47.50 g/l, while maximum loading for nickel(II) and manganese(II) is 2.50 g/l and 10 g/l respectively. Besides, the equilibrium data obtained is better fitted to Langmuir isotherm model. Throughout this study, conclusion could be made that among of these three metal ions, copper is highly selective towards the selected resin.
