Many gold plants use a blended collector or separate collectors as needed based on mineralogy and ore chemistry. Copper sulfate is commonly used as an activator of gold-bearing iron sulfides in flotation plants. The dosage, addition point, and the slurry pH range are critical parameters for maximizing the benefits from copper sulfate.

Gold flotation is widely used in the case of refractory ores, in which small-sized gold particles, locked within sulfide minerals, are recovered through flotation of gold-bearing minerals (Marsden and House, 2006). It is also an effective means for separating free gold from silicate particles present in ore.

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. …
