Effect of particle size on the froth floatation of sokoto phosphate ore for its beneficiation has been investigated and established. the research has been conducted using various reagents phs at different sieve size fractions. bench scale flotation tests were carried out on -250180 m -180106 m -10675 m -7545 m and -4538.
Environmental impact of flotation processing . valuable minerals in an ore can be separated from each other and from worthless minerals by the froth flotation process. the need for a process to extract ore arose from major sulfide mineralization after the oxide ores had been depleted.

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. see flotation. this article was most recently revised and updated by erik gregersen senior editor.
Froth layer. particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. the recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.
Froth. the mineral ore particles become wet by oil while the gangue impurities particles by water. 5in the floatation tank a current of compressed air is circulated through the water. a rotating paddle agitates the mixture and draws air into it. as a result froth is formed which carries the mineral particles. the froth .
