Gold flotation is an important method of extracting gold.

Gold flotation is the use of gold mineral surface hydrophobic particles themselves or under the action of flotation reagents or increase hydrophobicity.

Gold mineral particles in liquid – gas or water – oil interface aggregation occurs.

Although the density of these gold particles, but can be used with bubble flotation affinity was floating on the surface of the ore fluids, then these gold particles containing foam for recycling.
