Most limestone is made into crushed stone and used as a construction material.Historically, limestone had been mined for crushed stone, lime and cement production, and building stone. Lime is produced by dissociating the chemical constituents of limestone, which is composed of the mineral calcite (CaCO3), by heating it to temperatures up to 1300 C.The Cement Manufacturing Process Advancing Mining Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 C in a cement .Cement manufacture, like many other manufacturing processes, begins at the mine, where the raw materials like limestone, silica, aluminates, feric minerals and others are obtained. Some typical materials used for calcium carbonate in cement manufacturing are limestone.
