An overview of the beneficiation of iron ores via reverse

Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be applied to reduce the silica content in magnetite concentrates obtained using wet low-intensity magnetic separation.

2/1/2005· Concurrently, the USBM branch in Minnesota developed the reverse cationic flotation route that eventually became the most feasible approach for iron ore flotation in the USA and in other western countries. The first applications of reverse cationic flotation relied upon fatty amines, later replaced by the more efficient ether amines.

Collecting Agent–Mineral Interactions in the Reverse

A common task in the reverse flotation of iron ores is to separate quartz from iron oxides as quartz is often the major gangue mineral in iron ores. In some iron ores, removal of non-quartz gangue minerals is also essential, which has been the subject of several studies [ 16, 19, 20, 21, 22, 23 ].
