steps involved in the extraction of iron ore

Aug 21, 2020· Ironmaking, the firststepin making steel, involves the raw inputsof iron ore, coke, and lime being melted in a blast furnace. The resulting molteniron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.

  • Processes and Procedures in the Extraction of Iron

    The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials areloaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
