iron ore extraction process
The Extraction of Iron Chemistry LibreTexts
Extracting iron from iron ore using a Blast Furnace The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke Coke is produced by heating coal in the absence of air Coke is cheap and provides both the reducing agent for the reaction and also the heat sourceThe 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 tuyeresProcesses and Procedures in the Extraction of Iron
