GCSE CHEMISTRY

Extraction of Metals. Extraction of Iron.. Chemistry of the blast furnace ().. Limestone is calcium carbonate (CaCO 3) and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates).

Uses of stone

Mostly used in roads, concrete and building products.
