The long residence time of the gold within the grinding circuit can cause some of the GRG tobecome nongravity recoverabledue to smearing on togrindingmedia, mill liners and gangue minerals. This effect is minor as more than 98% of the GRG entering the ball mill remains gravity recoverable after grinding (LaPlante, 2000)

Grinding and Classification. The Steel Head Rod Mill has proven extremely satisfactory for grinding such pegmatitic mineral as feldspar and spodumene. The grinding circuit should have a controlled feed rate which is accomplished with a Adjustable Stroke or variable-speed Belt Feeder.

These grinders are used for grinding round and hollow jobs whether the internal surface of this job is completely round, ditched round, or is in taper. Small grinding wheels of 3 cm to 5 cm, are used in such grinders. Sometimes grinding wheels of special shape 0.2 cm to 0.3 cm. These grinders can be divided into two parts. a. Chucking Grinder
