Abstract: In the recovery of noble metals, including gold, silver and members of the platinum group, the ores or tailings are subjected to the action of various leaching agents, namely, sodium cyanide, thiourea, chlorine and aqua regia and optionally a leaching aid, such as chloride ions. The resulting slurry is then diluted to an optimum pulp density of 0.1 to 10.0% and allowed to stand in a holding tank for periods up to 30 minutes, preferably 15 minutes, with the optional addition of a dispersant, such as sodium silicate, sodium carbonate, trisodium polyphosphate or sodium hexametaphosphate. The pulp is then centrifuged to remove solids if necessaryand is then passed at a pH
