Clinker quality depends on raw material composition.
Portland cement is the most common type of cement in the world. It is used primarily to make concrete mortar and grout. Portland cement manufacturing 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
Cement Extraction and processing Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones slates and some shales with the aid of blasting when necessary.

Advances in Materials Science and Engineering Hindawi
The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings IOT) to replace clay as aluminasilicate raw material for the production of Portland cement clinker.
Raw materials for cement manufacture. The first step in the manufacture of portland cement is to combine a variety of raw ingredients so that the resulting cement will have the desired chemical composition.
