The froth flotation process was patented by e. l.sulman, h. f. k. pickard, and john ballot in 1906, 19 years after the first cyanide process patents of macarthur and the forests. it was the result of the intelligent recognition of a remarkable phenomenon which occurred while they were experimenting with the cattermole process.

Froth flotation is a process used for selective separation of hydrophobic materials from hydrophilic. over the years, various criteria have been introduced for evaluating flotation circuits. technically, grade and recovery are the most common indicators for evaluation of a flotation circuit performance.
Froth flotation process for the recovery of minerals and a . mar 13, 1990018332a flash flotation process, by definition, involves a relatively short flotation time. accordingly the flotation times for example 8 and 9 were as short as two minutes. a longer flotation time would have resulted .
In flotation, the technician places dried soil on a screen of mesh wire cloth, and water is gently bubbled up through the soil. less dense materials such as seeds, charcoal, and other light material called the light fraction float up, and tiny pieces of stone called microliths or micro-debitage, bone fragments, and other relatively heavy materials called the heavy fraction are left behind ...

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. the selective separation of the minerals makes processing complex that is, mixed ores economically feasible.
