A Simple Introduction on the Magnetite Reverse Flotation ...

2015-10-22  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 the concentrate is an important ...

Effect of reverse flotation on magnetic separation ...

2012-8-9  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). In this study, the effect of reverse flotation on the optimization of products obtained from magnetic ...
