Frothers behaves as Soap How much frother is needed for proper flotation? A common feature of most commercial frothers is their heteropolar nature, consisting of a non-ionic polar group (or groups) exhibiting a hydrophilic character coupled with a hydrophobic non-polar character.

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an …

Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

Yet if the ore mineralogy is too widely and finely disseminated for other methods, then he thinks flotation could potentially be an effective first concentration step. More widespread interest is directed toward ore sorting, which can help toss out gangue early on and features heavily in mine-to-mill discussions.
