Iron ore mining and dressing

Froth flotation. In froth flotation, the different wettability between the iron compounds and the undesirable gangue is used. While, for example, water is wettening the gangue relatively well, i.e. adheres to them, water tends to roll off the ferrous particles. This effect can finally be used to separate gangue from iron compounds.Web

The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores. It can be applied as either the sole concentration process or as a final concentration stage to ensure a high-grade product. In the flotation process, air is bubbled through a suspension of fine iron ore in waterWeb
