(PDF) Copper–gold ore processing with ion exchange

Because of the copper minerals in the Gedabek ore, the PLS contains high concentrations of copper (see Table 3); typically the Cu/Au concentration ratio in the leach solution is $1000 and, under these conditions, it is not practically feasible to use conventional activated carbon to adsorb the gold. The technology used at Gedabek to extract ...
