Limestone—A Crucial and Versatile Industrial Mineral

Limestone—A Crucial and Versatile Industrial Mineral

imestone, as used by the minerals industry, is any rock composed . mostly of calcium carbonate (CaCO. 3). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it a

Jan 29, 2014 To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete
