GRAVITY CONCENTRATION OF GOLD FROM CYCLONE FEED

bypass the gravity concentration circuit and report straight to cyclone overflow. Treating even a fraction of cyclone feed, properly biased, will result in higher recovery through an enhanced gravity concentration circuit. Downstream Processes In theory, downstream processes such as froth flotation and cyanide leaching will recover all of the
