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. …

Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
