    Vales VALE Lackluster Q1 Production Boosts Iron Ore

    By 1350 BC to 1100 BC, the production of ferrous metals from iron ore had spread to a wide geographic area. 1 More than 3,000 years after this early beginning of the Iron Age, modern iron and steelmakers still use the same carbothermic process discovered by early ironmakers. However, this industry continues to develop incremental and entirely ....Not all iron ore is created equal. The highest quality and most important iron ores for steelmaking are hematite Fe2O3 and magnetite Fe3O4. Hematite is the more sought-after ore and the preferred raw material in efficient steelmaking mills. It accounts for approximately 95 of South Africas iron ore production.
