  • Gold Geoscience Australia

     · Fine gold in crushed ore will be processed differently depending on the nature of the gold ore itself. 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
