Free-milling ore is the name for when gold can be recovered by crushing, grinding and cyanidation (treatment with a dilute cyanide solution) without additional processing. In refractory ore the gold is locked in sulphide minerals, so to achieve satisfactory levels of gold recovery additional processing is required before cyanidation.
