Froth flotation is a method of mineral separation in fluid which relies on the difference between the chemical composition of minerals compared to gangue. Flotation cells (tanks of fluid) are aerated to produce bubbles. The high-grade mineral particles attach to the bubbles, which rise to the surface and form a froth which can then be recovered.
