Flotation of Iron Ore: A Brief Review MDPI

The route of reverse ﬂotation is currently in widespread use in iron ore ﬂotation practice. The majority of studies on reverse ﬂotation of iron ore focused on reagents and reagent scheme [913]. The reverse ﬂotation route can be classiﬁed into reverse cationic ﬂotation and reverse anionic ﬂotation, based on the collector type.
