Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist. Commercially, the term limestone includes dolomite, dolomitic limestone, oolitic limestone, and travertine

About Limestone. Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite or aragonite. It is a kind of stone widely found in nature. Limestone can be directly processed into stone using crushing equipment and fired into quicklime. Quicklime absorbs moisture or adds water to become hydrated lime.

and washing it removes impurities. Calcining is the heating of limestone to convert the calcium carbonate into calcium oxide. This process is typically carried out in a rotary or vertical shaft kiln. Required temperatures of the kilns exceed 1800 degrees. The product of calcining is quicklime which can be used as "pebble lime" or may be crushed or

Limestone is part of the charge used when extracting iron from its ore. Limestone is primarily composed of a calcium carbonate compound and is not referred to as coke. When calcium carbonate decomposes as a result of the high heat inside the furnace, it reacts with sandy impurities to form what is known as slag.
