Abstract
Commercially available ion exchange resins with the iminodiacetate functional group have been evaluated for their suitability for the adsorption of nickel and other metal ions from the tailings resulted from the pressure acid leach process. The resin with the highest nominal capacity was observed to adsorb less nickel as a result of the adsorption of greater amounts of the impurity ions. The equilibrium loading for nickel on the preferred resin was found to be similar from the ammonium and protonated form of the resin although the kinetics of adsorption is greater when the resin is initially in the ammonium form. A study of the kinetics of the loading of nickel and cobalt from pulp has shown that the rate can be described in terms of a first order approach to equilibrium.
