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.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated well ground minerals/metals and making/playing on making them hydrophobic water-repel individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents:
Froth floatation is a method of separation of minerals or particles, by taking advantage of the differences between their superficial proprieties in a water solution. It is a mineral processing technology that involves three phases, solid, liquid, and froth. Solid refers to particles bearing minerals.
Froth flotation, separation of minerals differing little in density but greatly in wettability by surfactants that stabilize a froth formed on the surface of an agitated suspension of the minerals in water.
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.
Froth flotation is the most widely used phosphate ore separation process. Because of the nature of the phosphate ore, such as mineral types and content, disseminated particle size, its separation difficulty and flotation types varies.
An improved method in concentration of oxide ores and minerals by froth flotation process which comprises subjecting a pulp of mineral slurry to the combined action of a organic nitrogen compound with one or more NH 2 group and hypochlorite in a slightly acid pulp of mineral slurry. The decomposition of the NH 2 group provokes a highly oxidizing state in the mineral slurry, a state which can
