· Although direct anionic flotation was the first flotation route employed in the iron ore industry, it was later largely replaced by the more efficient reverse cationic flotation route. The application of reverse anionic flotation in China in recent years effectively overcomes some flaws of reverse cationic flotation such as high reagent cost and high metal loss in desliming

The mineral processing technology of Anshan-type ores has been developed in a rapid speed in recent years, and the combined flowsheet at the core of anionic has become a mainstream in the beneficiation of Anshan-type ores in china. With the successful application of this combined flowsheet, some obvious problems are also emerging

slimes [5]. When the test sample contains relatively lesser gangue, it is easier to float it and hence can be employed rather than direct where in major proportion of the material, otherwise, would have to be floated. As such, the is the usual for the beneficiation slimes

Hongxing increased anionic reverse flotation process of magnetic concentrate on the basis of the single magnetic separation process. Iron ore concentrate was obtained directly with a roughing, tailings were discarded with three scavenging, middlings returned to efficient thickener. Finally, iron concentrate was increased from 64.25% to 67.22%

Vale is the largest producer in the world. Since the 1970s, Vale has been using cationic to remove siliceous impurities from its ores. Whilst this has operated effectively for many years, it suffers from the problems of high reagent costs and high metal loss

forced producers to re -examine their 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. silica is floated away from the

reverse flotation is usually pH dependent process and is done effectively at lower pH range from pH 9 to 10 as compared to anionic flotation which is done for pH range from pH 11 to pH 12 Ana et al., 2017 [10]. However, even with these technologies, it could not build a
