2020111 · The typical feed to a flotation system in the iron ore industry consists of particles in the size range between 10 µm and 300 µm. The slimes fraction (<10 µm) are removed using hydrocyclones prior to flotation and the top size is limited to 5–10% greater than 150 µm. Flotation is performed in circuits consisting of mechanical cells ...
