  • It can be used for remineralizing and increasing the alkalinity of purified water to prevent pipe corrosion and to restore essential nutrient levels.
  • Used in blast furnaces, limestone binds with silica and other impurities to remove them from the iron.
  • It is often found in medicines and cosmetics.
  • It is used in sculptures because of its suitability for carving
