Developments in the physiochemical separation of iron ore
Jan 01, 2015The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.

Silica and Iron Recovery from a Residue of Iron Ore Flotation
Ferric oxides are separated from silicates by flotation or magnetic separation. The residue generated by magnetic separation consists of fine iron oxide and silicates. Two types of residues are generated by flotation. One of them is similar to sand and consists of quartz particles (greater than 85 wt%) and iron oxides (less than 15 wt%).

Froth Flotation an overview ScienceDirect Topics
The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10]. Flotation technologies are now widely
