Flotation of silicates gangue from hematite containing ...

concentrates with weak silica content and satisfactory iron recovery were obtained by reverse cationic flotation, when it was fed with iron preconcentrate 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.
