The Metallurgy of Cyanide Gold Leaching – An Introduction
At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at high temperature and pressure with sodium hydroxide and cyanide solutions to form a high value electrolyte solution. Gold bullion is then recovered from the electrolyte by electrowinning. That much is straight forward.
