Iron Ore Reverse Flotation Machinery

The reverse flotation process of iron concentrate is used to reduce the impurities in the iron concentrate. In the ball mill grinding process, the raw ore is ground to -0.074mm, accounting for 60%, and the magnetic separator is used for magnetic rough separation. The magnetic field strength is 96kA/m.

Reverse Flotation Of Iron Ore - greenrevolution.org.in

09/05/2020 Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.
