Crushing and Grinding: Rock gold is often embedded in hard rock, and the rock first needs to be ground and broken to release the gold ore. Gravity separation: Similar to placer gold, rock gold can also be initially separated by gravity separation. This can be achieved using vibration tables, centrifuges, spiral chutes and other equipment. …
