The concentration process produces a non-magnetic tailing containing apatite, with grades between 1–3% P[sub.2]O[sub.5] [9]. Flotation is a method based on the difference in physicochemical properties between valuable minerals and gangue [10]. The wettability of the surface plays a decisive role in its buoyancy.

Three different low grade tailing materials, 2.8-7.2 % P2O5 content from LKAB's magnetite beneficiation process have been extensively tested as feed material for apatite recovery by froth flotation. The three tailing materials were tested in a froth flotation pilot plant that contains all processing steps as in a full-scale froth flotation plant.
