Step 1: Mining. The first step of Cement manufacturing process is to quarry the principal raw materials, mainly limestone, clay, and other materials. Step 2: Crushing. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches.
Quarrying is the process of removing rock, sand, gravel or other minerals from the ground in order to use them to produce materials for construction or other uses.

Cement – if limestone (or its variety chalk) is mixed with clay or sandstone before firing, it can produce Portland cement which when mixed with aggregate makes concrete. Stone from Mendip quarries has been employed in all of these ways (with the exception of Portland cement manufacture).
Quarrying is used mainly in the production of construction and building materials, such as solid stone or crushed rock for aggregates, or for raw materials for processes such as cement manufacture. As a technique, quarrying is normally only used where raw materials of adequate quality and size cannot be obtained economically by other means.

If the finished cement is used to manufacture concrete structures, such as culverts, this is no longer mining under MSHA, but manufacturing under OSHA. Similarly, a gypsum mine will extend through product milling, but when product is transferred to a wallboard manufacturing plant on the same property, it goes from MSHA to OSHA.
