Manufacturing Process Continental Cement

Step 1: Quarry. For its raw materials, cement manufacturing uses minerals containing the four essential elements for its creation: calcium, silicon, aluminum, and iron. Most plants rely on a nearby quarry for limestone. The most common combination of ingredients is limestone coupled with much smaller quantities of clay and sand.

Hope Cement Works Wikipedia

The shale beds are to the north and east of the works, whereas the limestone is to the south. A byproduct of the lime quarrying process is the mineral fluorspar, which is used as a chemical feedstock. Originally, the cement was made with a 'wet' process, which used two kilns, with two more added in the 1930s and a fifth in 1952.
