Introduction to the concepts of reversible reactions and a dynamic chemical equilibrium through detailed explanation and example descriptions. Limestone - a very useful material. Crushed limestone is used as roadstone, construction fill, iron smelting, ceramic wall tiles and flue gas desulphurisation. Extraction of Metals. 13 Name some uses of lime and slaked lime as in treating acidic soil and neutralising acidic industrial waste products, e.g. Get Price. Extraction of Metals. This is called thermal decomposition (see examples of other carbonates). industrial line for manufacture of sand from limestone. A concrete made from a mixture of lime sand and gravel is said to be as lime concrete. Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. flue gas desulfurisation Quarrying or mining. Limestone consists mainly of calcium carbonate, CaCO 3; Lime which is calcium oxide, is manufactured from calcium carbonate by thermal decomposition:; CaCO 3 → CaO + CO 2. 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. Limestone, is a sedimentary rock formed by the mineral and 'shelly' remains of marine organisms, including coral, that once lived in warm shallow fertile seas..
