Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water.The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.
57 International Journal of Mining Engineering and Mineral Processing 2012, 1(2): 56-61 into the flotation pulp from mineral particles or occur from hard water. Although the reverse cationic flotation route has become the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some

Flotation is also used to remove impurities before hydrometallurgical treatment (ie, carbon pre-flotation) to purify low-sulfide and refractory ores for further processing. Flotation is considered to be the most cost-effective method of concentrating refined gold and is often used in conjunction with flotation …
Flotation is a complex physico-chemical process which is the most widely used in mineral processing technologies. [1] In 1905, Potter introduced flotation in the mineral industry. [2] The first ...
Mineral processing is the art and technology of treating ores from the mining areas in order to separate the valuable minerals from the waste rock. It includes processes to provide a more concentrated material for the procedures of the following extractive metallurgy. The two main processes to increase the concentration of minerals are leaching and flotation.
Oct 31, 2016· Thus, flotation initially originated from the field of mineral processing, usually termed "froth flotation"; a typical application is certainly with sulphide minerals. For many years, various particulate solids, in addition to minerals, have been extracted from water by using this effective process.

Abstract. In the extraction of metals from their ores, the process of mineral flotation plays a most important role. Flotation provides the means of separating and concentrating the valuable components of an ore to produce a grade of mineral concentrate suitable for feeding to efficient pyrometallurgical or hydro-metallurgical operations.

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles …
Flotation is now the most important mineral beneficiation method. Froth flotation as practiced at present was preceded by many attempts to float minerals using certain oils such as pine oil: certain mineral particles clinged to the oil layer which is lighter than water, hence it was floated. For example, the process used by William Haynes in
