Run-of-Mine (ROM) ore is crushed and ground in semi-autogenous (SAG) and ball mills, free gold is recovered in a gravity circuit and flotation is used to recover a sulphide concentrate. This is then oxidized using autoclaves, producing feed for conventional carbon-in-leach (CIL) cyanide leaching to recover the contained gold.
