The primary cement manufacturing process involves the mining of raw materials, mainly limestone and clay, which are used in cement manufacturing. In most of the cases, the limestone and clay are excavated from open cast mines by drilling and blasting and other appropriate processes in mines.

The cement manufacturing process starts with the extraction and preparation of raw materials—a crucial phase that ensures the quality and consistency of the final product. Here, we explore the initial steps involved in creating cement, focusing on the mining and handling of key components like limestone, clay, shale, iron ore, and sand.

It is crucial to understand where cement comes from to make the process more sustainable. Cement is an essential ingredient to our world as we know it, but its production has room for growth. The mining and quarrying of precious minerals, the dust from grinding them, and the carbon emissions of the process all contribute to a nasty …
