Limestone MiningManufacturing IndustryChemical IndustryNeutralising AcidsConstruction IndustryIron and Steel IndustryMining is much more expensive compared to quarrying and so it is rarely carried out. For a limestone to be economically mined, it would have to be either particularly pure for industrial processes or in high demand as a special building stone.

Lime Production: Industry Profile
Limestone can be categorized as either high calcium or dolomitic. Pure high-calcium limestone is 100 percent calcium carbonate (100 percent calcite or aragonite). Generally, limestone of this purity does not occur naturally. High-quality, high-calcium limestone would actually contain 97 to 99 percent calcium carbonate and 1 to 3 percent impurities.get price
