this method of extraction works because carbon is more reactive than iron so it can displace. iron from iron compounds. extracting a metal by heating with carbon is cheaper than using electrolysis.
extraction of iron step1: concentration the ore is crushed in crushers and is broken to small pieces. it is concentrated with gravity separation process in which it is washed with water to remove clay sand etc. 8. steps of extraction step1: concentration step2: calcination the ore is then heated in absence of air (calcined).
