Collecting Agent–Mineral Interactions in the Reverse Flotation of Iron
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 [9,10,11,12,13]. The reverse flotation route can be classified into reverse cationic flotation and reverse anionic flotation, based on the collector type.
