Flotation Cells in Iron Ore Processing - Froth Flotation ...

The induced air flotation cell has the rotor position at the top of the cell as it needs to be close to the surface to pull in air; hence the majority of the mixing energy is dissipated in the top of the cell. True these cells are designed for pumping and circulating pulp throughout but as the high energy zone is generally adjacent to the rotor you would have to put in even more energy to ensure that particles entering the

Investigation of the reverse flotation of iron ore in ...

This paper investigates the reverse flotation of iron ore in a laboratory mechanical, oscillating grid (OGC) and pneumatic flotation cell. The main objectives are to investigate the recovery of coarse quartz (+150 µm) by flotation and fine hematite (−25 µm) by entrainment. Agitation/energy input results show that coarse quartz recovery increases with increasing impeller speed to a maximum of ±70%. The recovery of coarse quartz in the OGC is ±10% higher than in the mechanical cell
