flotation of low grade iron ore

The magnetite grade in the iron concentrate of the anionic flotation is increased up to 26.0% while the grade of non-metallic minerals is decreased to 1.2%. Hematite and magnetite liberation in both flotation tails is almost similar and equals 70% and 60%,

Froth Flotation of Iron Ores

China is far behind western countries given that only 5% of its iron ores have a grade over 50%, and the average Fe grade is around 33%. These low-grade iron ores need to be enriched before smelting (Liu et al., 2011).
