The main reason is that aphanitic graphite has good natural floatability and is easy to mud. In the flotation process, aphanitic graphite competes to adsorb reagents and float up, which seriously affects the flotation recovery of gold. There are two processes: pre decarburization – flotation gold and inhibition carbon – flotation gold.

July 23, 2014. Most methods of water-based gold extraction are dependent on gold's lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).
