Cement - Extraction and processing | Britannica
Cement - 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. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.

AN INTRODUCTION TO THE CEMENT …
In the cement industry, the quarry is the extraction method for the production of raw materials in the cement manufacturing process. Quarry extraction describes the extraction of rocks on the surface, while open-pit extraction describes the extraction of minerals on the surface. Discontinuous mining systems, such as scraping, tearing, crushing, and blasting, are commonly practiced in limestone ...
Cement Analysis and Production Information | …
The cement production process begins with the extraction of limestone and clay from the quarry. The material is then blended, crushed and fed to the kiln. Post-kiln, the clinker is cooled and goes through a final grinding method before it is ready to ship. Portland cement, the most common type of cement, is formulated in a variety of strengths and colors, depending on its intended use. Cement ...
