Gravity Concentration of Gold From Cyclone Feed In

GRAVITY CONCENTRATION OF GOLD FROM CYCLONE FEED IN GRINDING CIRCUITS By Steve McAlister, P. Eng., Colin Sprake, B. Sc. Introduction. The use of gravity concentration in gold milling flowsheets is well established. In the past, a typical approach was to treat the entire mill discharge with a mineral jig.

The downfeed is applied (a) in plunge grinding at each or either end of the table travel, and (b) in transverse grinding at each reversal of the cross feed. In plunge type surface grinding where the entire width of the grinding wheel must penetrate into the work material to the full amount of the downfeed, the applicable rates are generally smaller than in transverse grinding.
