    Precipitated calcium carbonate production process: first burn the limestone and other raw material sections to generate lime (the main component is calcium oxide) and carbon dioxide, then add water to digest the lime to produce lime milk (main component is calcium hydroxide), and then pass the carbon dioxide carbonized lime milk Calcium carbonate precipitates are generated and then prepared by

    How does weathering affect limestone? Internet

    2021-3-26 · Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.
