Limestone is a sedimentary rock, usually light in color, composed primarily of calcium carbonate with the occasional presence of magnesium. It is a porous calcitic rock that is commonly formed near hot springs. Most limestone is biochemical in origin meaning the calcium carbonate in the stone originated from shelled oceanic creatures. Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Source: National Stone Council

Description: The raw limestone limestone we process is yellow to light gray in color, depending on quality. Our limestone meets the calcium requirement approx. 36% of the feeds manufacturing industry; and the Calcium Carbonate requirement of approx. 91.5% of the coal fired power generation industry.
