Popis: The effect of the presence of a clay-laterite ore pulp (20–40 wt.%) on the adsorption rate of gold on activated carbon has been studied. A substantial reduction in the rate (e.g., by up to an order of magnitude) occurs when the pulp is present. The reduction in rate appears to be caused by two effects: permanent carbon pore blocking by ore particles and temporary shielding of the carbon particle surface, slowing gold access to the carbon as a result of the physical presence of the fine pulp. However, the pulp had no systematic effect on the equilibrium adsorption of gold on the carbon.
