Aug 09, 2012· 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 …

The cationic collector in the magnetite reverse flotation process is Lilaflot collector. When the dosage of the Lilaflot collector increase to 30-50g/t, the iron grade of the iron concentrate is up to 69.90%, the silica 2.80%, which is suitable for a direct reduction of iron concentrate. The sulfur content of …

concentrates with weak silica content and satisfactory iron recovery were obtained by reverse cationic flotation, when it was fed with iron pre-concentrate produced by high gradient magnetic separation. However, conducting the reverse cationic flotation implies a depression of hematite by starch and flotation of silicates by amine collectors.

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).
