Step 1: Mining. The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded ...

White cement is quite similar to standard grey cement; the only difference is in the manufacturing process, which results in a whiter product. White cement costs more than grey cement because it is produced in a more labour-intensive manner; the former costs around Rs 25 per kilogram, while the latter costs about Rs 7.
