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 Some deposits are mined by underground methods Softer rocks such as chalk and clay can be dug directly by excavators A conveyor draws raw material into the processing plant where it is washed to remove unwanted clay and to separate sand Sand separated during processing is dewatered and stockpiled Gravel then passes over a series of screens that sift the material into different sizes
