Extracting iron from iron ore. In the 12th century, men started to mine iron ore from rock. They learnt how to recognie rock that contained iron ore and broke off pieces of rock by lighting fires against it, to make it brittle. The work was done from the surface down, excavating the rock in opencast mines and following the veins of ore.Get A Quote
