In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer. Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out.

أكمل القراءةThis method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation. Magnetic Separation: This involves the use of magnetic properties of either the ore or the gangue to separate them.
أكمل القراءةThe ore is first ground to fine pieces and then passed on a conveyor belt passing over a magnetic roller. The magnetic ore remains on the belt and the gangue falls off the belt. Froth Flotation Method: This method is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in water.

أكمل القراءةFlotation 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.
