Kanger Ghati National Park Madarkonta and Kodri Bahar. These are Kotamsar cave, Kailash Cave, Dandak Cave, Devgiri Cave. Many other caves were also discovered in the national park. These caves have very fine structures of dripstones i.e. stalactites and stalagmites. Chemically these formations are recrystallized calcium carbonate. These structures have taken million of years to form. Kotamsar and Kailash caves are opened for tourists and other caves are closed for tourists. Only those caves which have openings have been discovered in the National park. There are many caves which have no opening and they are yet to be discovered. As approaches to most of
Calcium carbonate Calcium carbonate shares the typical properties of other carbonates. Notably, Calcium carbonate will react with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate. This reaction is important in the erosion of carbonate rock, forming caverns, and leads to hard water in many regions. An unusual form of calcium carbonate is the hexahydrate, ikaite, CaCO·6HO. Ikaite is stable only below 8 °C. The vast majority of calcium carbonate used in industry is extracted by mining or quarrying. Pure calcium carbonate (e.g. for food or pharmaceutical use), can be produced from a pure quarried source (usually marble).
