Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating

Flotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine.
