process involved in extraction of iron from iron ore

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 tuyeresThis concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top It is in the blast furnace that extraction of ironExtraction of Iron | Metallurgy | Blast Furnace and Reactions
