How Is Hematite Separated Out Of Iron Ore

How to Extract Iron from Hematite: Methods and Plants

Firstly, the raw hematite ores are evenly sent to a jaw crusher through a vibrating feeder for coarse crushing, then are sent to a cone crusher for fine crushing. Next, the ore is screened by a vibrating screen. Those whose particle size meet the requirements would be sent for grinding, while the others would return the cone c…

Hematite Separation Process

Hematite is iron oxide, a weakly magnetic iron mineral with an iron content of up to 70%. Mineral separation is the process of converting raw ore into high-quality products while meeting the market demand for steel production.

How is iron extracted from hematite?

Iron is extracted from hematite (Fe 2 O 3) in a blast furnace. In a blast furnace, the ore is led into the top of the furnace along with coke and limestone and the limestone is decomposed into the hot furnace, forming calcium oxide.
