The dissolved gold is readily adsorbed onto the carbon, thus removing it from solution, and the granular carbon is separated from the now barren ore by running the slurry through a screen. Gold is then leached from the carbon particles by a strong solution of sodium cyanide and sodium hydroxide, and it is recovered from solution by electrowinning directly onto steel wool or by the Merrill-Crowe process. In the latter process, …
