Features Of Calcite Calcite is carbonate and is generally white in colour. Calcite is a common constituent of sedimentary rocks, limestone in particular. It has the same chemical formula as other calcium carbonate based minerals like Limestone and marbles. Calcite, like most carbonates, will dissolve with most forms of acid. Calcite can be either dissolved by groundwater or precipitated by groundwater, depending on several factors including the water temperature and pH. Applications Pharmaceuticals Drilling Iron and steel industry
