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 …
Cement is manufactured by calcination of calcium, silica and alumina sources such as limestone, clay and sand [4].Generally, these raw materials are locally sourced and undergo several sequential operations such as quarrying, homogenising of raw meal, preheating, calcination, clinkerisation, cooling, grinding, storage and dispatch.
2. How is limestone used to make cement? Step 1. Limestone mining Cement manufacturing starts from the mining of raw materials, mainly, limestone and clay.

Mining has long been an important revenue generator in Mexico, contributing 8.3% of industrial GDP and 2.5% of national GDP. It is also a major job provider. In 2017, the sector supported 370,000 jobs directly and over 1.7 million jobs indirectly. Mexico's mining industry is undergoing significant restructuring.
Setting up a cement plant is both time and capital intensive; it could take anywhere between five to seven years from concept to commissioning and an investment of around to Rs 1,800-2,000 crore for a typical integrated plant of 3 million tpa cement capacity. Size of a cement plant could vary from 0.2 million tpa to 5.0 million tpa.
While each cement plant may differ in layout, equipment, and appearance, the general process of manufacturing portland cement is the same: crushed limestone and sand are mixed with ground clay, shale, iron ore, fly ash and alternative raw materials. Some manufacturers grind the raw materials dry, while others use a wet-grinding process ...
