· Limestone is used in iron extraction to remove impurities from the iron and becomes molten slag. The calcium carbonate (CaO3) in limestone catabolically reacts, forming calcium oxide(CaO) and carbon dioxide(CO2). CaO is highly reactive when subjected to the extreme heat of the furnace. CaO can react with impure iron, such as iron sulfide(FeS).

Limestone is a sedimentary rock composed of calcium carbonate (CaCO3). Limestone comes from the shells of dead marine organisms such as clams, oysters, crayfish, brachiopods, bryozoa, crinoids and corals. Such animals live on the bottom of the sea and after death their shells accumulate into piles, forming beds of limestone.
The Solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammonia-soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s.
