  • Steelmaking Wikipedia

    Steelmaking is the process for producing steel from iron ore and scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium and vanadium are added to produce different grades of steel.

  • STRATEGIES FOR PROCESSING LOWGRADE IRON ORE

    Oct 1, 2009 For example, many ores contain iron oxide in a nonmagnetic form and are so finegrained that it is uneconomical to grind them to a fine enough size to separate the iron oxides from the gangue. Exploitation of these iron minerals needs to take a different approach, using fewer process steps than are
