· ores in the form of hematite ferrous oxide and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit however, because does not occur naturally, it is necessary to use a blast furnace to separate or refine from the other substances in the .

To efficiently for high quality steel production, frequent grade monitoring, during all steps of downstream processing, is mandatory. Independent from the ironmaking method, the optimal use of fuels and energy during sintering, pelletizing and direct reduction DRI needs to be applied to stay competitive and ...

Iron ore is an important raw material for iron and steel production enterprises. After crushing, grinding, magnetic separation, gravity concentration etc, gradually we can get iron from natural minerals iron ore. It is the mineral aggregates that contain iron or iron compounds which can be used economically. Production Process of Iron Ore Generally, the processing of iron ore needs several processing stages, …
