2018-6-21 · 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.
