This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore (~-0.074 mm) going to froth flotation cells for recovery of iron. 4.In magnetite processing plant,the process of flotation separation is replaced by magnetic separation.
The flotation system in conventional iron ore flotation beneficiation processes is made up, for example, of rougher, cleaner and scavenger cells.Thus, the magnetic separator scavenged 46.9% of the iron from the flotation tailing. Additionally, prior to the WHIMS, the starting material tailing accounted for 54.9...
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.
