摘要: Activated carbon and resins readily adsorb gold from cyanide leach solutions. The main advantages of are its high selectivity towards gold, ease elution large particle size. On the other hand, do not suffer problems pore blocking by fine particles in slurry show superior adsorption kinetics higher loading capacity for gold. In addition, when used form fibre-reinforced sheets, many associated with beads overcome. experimental results shown to fit homogeneous surface diffusion model certain modifications occurs. Fritz Schluender isotherm is describe equilibrium behaviour adsorbed species. This reduces well-known Freunlich only one component (eg. Gold) need be considered.
