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.
In its simplest form, froth flotation is a method whereby minerals can be "skimmed" from the surface of "slurry" that is "ed" with the assistance of specific chemicals, water and air bubbles. MIBC is used as a frother in the flotation process in the mining of ores, .
a froth, which is removed as a flotation concentrate (a froth product) by skimming. The hydrophilic particles that are not floated with the bubbles remain in the pulp, and are removed from the cell as tailings. The typical industrial flotation cell, schematically shown in Fig., is referred to as a mechanical cell. There are other types of ...
Froth flotation, as a fundamental method for processing complex minerals, has been applied to research of surface chemistry of xenotime recently by several research groups. View Show abstract
Preface The process of froth flotation is an outstanding example of applied surface chemistry. It is extensively used in the mining, mineral, metallurgical, and chemical industries for separation and selective concentration of individual minerals and other solids.

Frothers are required to strengthen and stabilize air bubbles in the flotation system so the froth layer can be optimized for the system. Dow offers a range of glycol ether, polyglycol and alcoholbased frothers designed for a wide range of system conditions and requirements, from fine to coarse particle flotation.

A survey of a number of pyrite flotation plants using copper sulphate showed that in correct dosages it was able to increase both grades and recoveries. This was confirmed in .
Froth flotation is a process widely used to selectively separate valuable minerals from worthless gangue. The process relies heavily on the differences in the mineral surfaces' hydrophobic character to accomplish this task.
FLOTATION PROCESS Flotation is a method of separating an ore species froth another, based on its hydrophobic surface characteristics either natural or induced when present as a suspension in water with air bubble. Due to the affinity of the desired mineral to adhere to .

In froth floatation process sulphide ore is shaken with pine oil and water, the ore particles are adsorbed on froth that floats and the gangue particles settle down in tank. Thus, role of adsorption in froth floatation process can be understood as following processes.
