 ·  Iron ore, coke and limestone are the raw materials in making iron.  ·  Iron ore comes from China, Brazil and Australia.  ·  Iron ore is processed whilst in the blast furnace with the limestone, as the limestone removes impurities that could damage the strength of the final product.  ·  In the iron smelting process each product has its own use. The iron ore is iron but surrounded by impurities which need to be separated off, as only the iron is needed. Limestone removes these impurities. Leaving iron by its self.  ·  The ecological effects of using these raw materials are quite bad. A lot of the raw materials have to be imported from China, Brazil and Australia, the ecological damage of transporting millions of tonnes of raw materials across the world is very high. This could be reduced if the steel was made in these countries and transported to us. This would lessen the damage but not entirely.  ·  Scrap metal is used in the furnaces because it is cheaper and easier to recycle. The metal is of a poorer quality.
