Reverse Flotation Magnetite Amine

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 reagents ...

Abstract. Reverse flotation studies on magnetite samples have revealed that the use of starch as a depressant of Fe-oxides has a hydrophilic effect on the surface of Fe-bearing silicates and significantly decreases Fe in the silica-rich stream when used in combination with an amine (Lilaflot D817M).

Reverse flotation to remove quartz has been proved to be a very effective technique in the industry. Reverse cationic flotation of quartz uses mainly fatty amines and their derivatives as a collector, e.g. mono-amine, di-amine, and ether amine or a mixture of di-amine and mono-amine (Araujo et al., 2005).
