Abstract Limestone, or calcium carbonate-made of the skeletons of billions of sea creatures-is mined in large quantities. Carefully blasted out of the ground, it is first crushed with huge pestles to eliminate large boulders, then passed through a series of sieves to separate large chunks for further crushing. When sufficiently small, it is washed to remove clay, dust, and sand. The grades are separated: some for road-building, others for processing into sodium carbonate for glass-making. The sand from the wash is separated out and can be made into quicklime and subsequently into slacked lime; the remainder is processed to make cement powder.
