Aug 01, 2017 Limestone is one of the key minerals used in cement making. Limestone is a sedimentary rock composed mostly of the calcium carbonate (CaCO 3) and, according to the Mineral Education Coalition, comprises about 15% of the Earths sedimentary crust. Surface mining is the general excavation method.
Cement is a powdery substance made with calcined lime and clay. It is mixed with water to form mortar or mixed with sand, gravel, and water to make concrete, one of the worlds most versatile building materials. Relation to Mining. Cement manufacture requires an abundant, accessible supply of high calcium limestone or similar rocks.
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 Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8.

To make concrete, we mix sand and gravel, with cement. Cement is created by heating ground limestone with other minerals. When hot enough, the limestone releases carbon dioxide and becomes quicklime, the primary ingredient in cement. When the quicklime in cement reacts with water, it forms a stable crystal this is what happens when concrete ...
