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 ...Web

The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 µm up to 150 µm. The presence of the slimes (Ps < 10 µm) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to the increase on reagents …Web
