Gold Cyanide Adsorption on Activated Carbon

shell carbon was unclear (Tsuchida and Muir, 1986). Similarly, there is no consensus on the factors which determine the carbon- gold adsorption reactivity in a CIP plant and the selection of carbons for use in CIP plants has no broad scientific basis. We have therefore studied the fundamental aspects of gold adsorption on activated carbon.
