  • 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 are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeresThere are two equations, the first to describe how the carbon reacts with the oxygen in the air,Carbon + Oxygen Carbon Monoxideor2C + 02 2COTheWord equations for iron ore extraction? AnswersThe main steps in the sintering process are: Blending – a range of iron ore fi nes from different suppliers are blended with steelworks recycle materials Mixing – a reductant such as coke(PDF) Calculating the value of iron ores in ironmaking and
