Steps in the Modern Steelmaking Process

 · The resulting molten iron also referred to as hot metal still contains 4.5 percent carbon and other impurities that make it brittle. Primary steelmaking has two primary methods: BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. BOS methods add recycled scrap steel to the molten iron in a converter.

Principles of Extractive Metallurgy

What is Extractive Metallurgy ? Deals with extraction of metals from its naturally existing ore/minerals and refining them Minerals: Inorganic compounds with more than one metal in association with non-metals like S,O,N etc. Naturally existing minerals are sulphides, oxides, halides like: Hematite (Fe2O3), Magnetite (Fe3O4), Chalcopyrite (CuFeS2), Dolomite

How iron is made

The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag, which is produced in huge amounts.
