Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

Gold has varying modes of occurrence in sulphide ores ranging from being disseminated and interstitial in minerals such as lead and copper, in oxide ores particularly as disseminated particles, and as free milling gold or association with tellurides.
the valuable minerals in an ore are concentrated by froth flotation of crushed or ground ore; and, (b) this concentrate is smelted and converted into an even richer, low-iron sulphide matte. Representative concentrations before and after each of these steps are given in Table 1.2.

Learn the process of extracting Crude Metal from Concentrated Ore. Froth Flotation Process. Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals.
Froth flotation method is used for the concentration of sulphide ores. The method is based on the preferential wetting properties with the frothing agent and water. In the given options, Galena (PbS) is the only sulphide ore.
Only sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth.. This method is also used in waste recyling and paper industries.. this method also seperates hydrophobic substances from hydrophilic substances..

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.
Ore Concentration by Froth Flotation. Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation.
Froth flotation - Wikipedia, the free encyclopedia. The process was not froth flotation but used oil to agglomerate (make balls of) pulverised sulphides and buoy them to the surface, and was patented in 1898 with a descriptionIn the mining industry, the plants where flotation is undertaken to concentrate ore are generally known as concentrators or mills.
Supergene ores rich in sulfides may be concentrated using froth flotation. A typical concentrate of chalcocite can grade between 37% and 40% copper in sulfide, making them relatively cheap to smelt compared to chalcopyrite concentrates.
