Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is

A flux is used in both the iron and copper-making processes to get rid of impurities such as silica (SiO2) First the limestone (mostly CaCO3) is burnt ( ‘calcined’) in a kiln to form quicklime (CaO). This is added to the iron ore and reacts with the silica to form calcium silicate ( ‘slag’) which is then separated off from the molten

· Crushed stone is used for concrete aggregate, for road building, and, in the case of limestone, as flux in blast furnaces and for chemical applications. The quarrying technique consists of drilling and blasting to fragment the rock. A large number of charges are fired at one time, producing up to 20,000 tons of broken stone in one blast.
