Uses of limestone - Know About the Different Uses of Limestone
Limestone in powdered form is also used as a substance to absorb pollutants or control coal mine dust at many coal-mining facilities. Lime which is the byproduct of limestone is used to neutralize acids and treat wastewater, industrial sludge, animal waste, and water supplies. These are some popular uses of limestone.
Limestone - Wikipedia
Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Dolomite, CaMg(CO 3) 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium.Calcite in limestone is divided into low
