    Carrier flotation is a common technique used to improve flotation recovery of ultrafine ores. In this study we used coarse polystyrene as the carrier material to enhance flotation recovery of fine smithsonite (ZnCO3) particles. Sodium oleate was used as the collector and played a role in the adhesion of fine smithsonite to polystyrene due to its amphipathic properties. The carrier feature of

To liberate the Critical raw materials (CRMs) are of primary importance for energy storage systems as needed for electromobility. Many mineral deposits which contain CRMs are low-grade ores. To liberate the CRMs a grinding of the mineral ores to very fine sizes below 20 µm particle size is necessary.

    Turbulence plays a role as does bubble‐particle aggregate velocity and bubble size. The stability of the bubble‐particle aggregate controls the maximum floatable particle size of coarse particles. For fine particles the flotation limit is dictated by the energy required to rupture the intervening liquid film between the particle and bubble.
