According to some estimates, around 180-250 kg of coal and about 1.5 tonne of limestone is required to produce a tonne of cement. Cement manufacturing consumes minerals such as gypsum, Quartz, bauxite, coal, kaolin (china clay) and iron ore too in varying amounts. Limestone is also a leading contributor to the Indian exchequer in terms of value
