Iron Ore Reverse Flotation Process

The cationic reverse flotation of quartz is the most commonly used route quartz is floated with ether amines partially neutralized with acetic acid, and the iron ore is depressed by unmodified starches ().The cationic reverse flotation of quartz is preferred for iron ores, due to the high selectivity achieved and the fact that the iron bearing minerals are in greater portion than the gangue.

    Forced iron ore producers to re examine their process flowsheets and evaluate alternate or supplemental processing routes. The requirement for higher quality pellets demands that the silica content be lowered to levels ranging from 2.0 SiO 2 to below 1.0 SiO 2. Reverse flotation (silica is floated away from the iron.Iron ore slimes [5]. When the test sample contains relatively lesser gangue, it is easier to float it and hence reverse flotation can be employed rather than direct flotation where in major proportion of the material, otherwise, would have to be floated. As such, the reverse flotation is the usual process for the beneficiation of iron ore slimes.
