Explain the process of steel making from iron ore.
An iron-ore is a mineral substance that, when heated, yields metallic iron. Smelting of iron-ore is heating up the mineral with coal and limestone in an industrial oven to extract the iron. Molten iron is purified and converted into steel in a basic oxygen furnace by adding alloy metals.
© IEA ETSAP
PROCESSES AND TECHNOLOGY STATUS – The basic materials for iron production are iron ore, coal and coke (also used as energy input to the process) or alternative reducing agents, limestone and dolomite. Steel production requires iron, steel scrap and lime (burnt limestone). The iron ore is smelted to produce an impure metal called "hot metal"
