  • European perspectives on the extractive metallurgy of

    2017-4-28 · At the Seventh European Coke and Ironmaking Congress in Linz on September 12–14, 2016, attention focused on the prospects for the development of ferrous metallurgy. The combination of a blast furnace and an oxygen converter is expected to remain the primary system for smelting steel, until electrosmelting becomes dominant in the 2060s. The development of hydrogen metallurgy

    The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes. Limestone is then added as flux, and it creates the slag. Impurities such as S, Si pass into the slag and the slag later can be easily separated to yield pure iron. Test your Knowledge on Iron extraction blast furnace metallurgy!
