Cement - Extraction, Processing, Manufacturing: 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. The …
include carbon dioxide released during energy generation to power cement manufacturing plants. Worldwide it is thought that cement making is responsible for around 7% of total man-made CO 2 emissions. The UK cement industry has agreed to reduce its primary energy consumption by 25.6% per tonne of cement produced by 2010, from a 1990 baseline.
The cement production process 1. The Quarry: The cement production process begins with the extraction of limestone and clay from the quarry. 2. Crusher and Pre-Blending: The material is then crushed to reduce particle sizes and blended to reduce variability in composition. 3. Raw Mill and Kiln: Raw materials and additives are

Cement manufacturing: components of a cement plant. This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant - the kiln, the cement mill etc.. For information on materials, including reactions in the kiln, see the ' Clinker ' pages.
The basic chemistry of the cement manufacturing process begins with calcination, the decomposition of calcium carbonate (CaCO 3) at about 900 °C to leave calcium oxide (CaO, lime) and liberate gaseous carbon dioxide (CO 2).This is followed by the clinkering process in which the calcium oxide reacts at high temperature (typically 1400–1500 °C) with silica, …
Generally cement plants are fixed where the quarry of limestone is near bye. This saves the extra fuel cost and makes cement somehow economical. Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing.
