Jul 10, 1973· In the recovery and concentration of iron minerals from magnetic or nonmagnetic iron ores, it is the undesirable silica and miscellaneous cherts and siliceous materials that are floated away. The desired concentrated iron minerals remain. Froth flotation is well known in the art for separating or concentrating minerals from ore.
Jun 23, 1992· In another type of flotation scheme called reverse flotation, the undesired mineral, such as silica or siliceous gangue is floated away from the valuable minerals which are left in the tailings. A wide variety of compounds are taught to be useful as collectors, frothers and other reagents in froth flotation.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

The Jameson Cell can be used for the reverse flotation of silica from iron ore, where flotation columns have traditionally been used. Phosphate flotation. Phosphate processing operations that use flotation as the principal mechanism to concentrate the phosphatebearing minerals usually discard particles smaller than 20 µm in diameter.
Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
