<p>A precious metal, particularly gold, is recovered by adsorbing a dissolved compound of the metal from solution onto a cloth consisting of fibres of activated carbon. The solution may be obtained by leaching an ore or similar material. The precious metal may be recovered by stripping the adsorbed material with a solution containing cyanide. Alternatively the loaded cloth is suitable for use as an anode in an electrolytic recovery stage.</p> |
