Mining - Flotation One of the most widely used methods of recovering valuable minerals in the mining industry is using froth flotation tanks. Inside these tanks, the ground ore is mixed with water to form a slurry. Hydrophobic materials then separate from hydrophilic materials through the use of chemical additives.

Flotation separates valuable minerals (copper, lead, zinc, iron, and phosphate too) from the contaminating minerals in the ore (sand in this case). In the direct flotation process the valuable mineral is coated with a special hydrocarbon (fatty acid) that makes coated particles behave the same as a waxed car.
