Extraction of iron from iron ore

How is Iron Extracted from Iron Ore. Physical Science. Iron is an element that has the chemical symbol, Fe. It is a metal that has been used since prehistory, by the Ancient Egyptians and Sumerians as early as 4000 B.C. These ancient peoples were able to get pure iron from meteorites that fell to the earth, and they used it in the tips of

    Extracting iron from iron ore . In the 12th century, men started to mine iron ore from rock. They learnt how to recognize 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

    Feb 15, 2021 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 tuyeres
