The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1 Quarrying The raw material for cement manufacture is a rock mixture which is about 80% limestone (which is rich in CaCO3) and 20% clay or shale (a source of silica, alumina and Fe2O3). These are quarried and stored separately.

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.

Some limestone which is high grade could more profitably be used as paper filler than for the manufacture of cement. Tests were performed to examine the characteristics of the pulverizing system.

Equipment to reduce dust emissions during quarrying and manufacture of cement is widely used, and equipment to trap and separate exhaust gases are coming into increased use. Environmental protection also includes the reintegration of quarries into the countryside after they have been closed down by returning them to nature or recultivating them.

Limestone is a rock composed of calcium carbonate (CaC03). It is the rock type most commonly used to make crushed stone in the United States. It holds this position because it is widely available and suitable for a greater diversity of uses than any other type of rock. Limestone can be used to make cement. It is the primary ingredient of concrete.
