They are widely used as building materials and raw materials in various industries. Limestone, also known as magnesium limestone, is a popular natural stone. Magnesium carbonate and calcium carbonate form this sedimentary carbonate rock. The product comes from high quality limestone quarries throughout Turkey, and is processed and made ready.
