    Various leaching processes are known for extracting precious metals (e.g., gold, platinum, silver) from minerals. In known processes, a leaching liquor dissolves gold from an ore into a stable solution phase containing gold ligand (i.e., lixiviants). The dissolved gold is collected by a recovery process, to produce solid gold metal.
