    Previous work showed that about 45% calcium carbonate in asbuton rock could be dissolved into the mixture of carbonic acid and 0.5 M NaCl at 3 bar and 90 °C. 27 However, the reaction conditions in their works are harsh and the dissolution efficiency is low. Furthermore, little information about the detailed reactions during the extraction was reported, as well as the mechanisms. It is ...

    Calcium Carbonate as Food nutrition enhancer - mineral mussel

    Calcium carbonate is converted to lime by the loss of CO2, which is used in construction, iron extraction and steel production as aiding melt and for the preparation of calcium carbide. Lime is also used in agriculture to modify the soil and adjust its pH. Calcium carbonate is used in the ceramic tile industry, especially the glazing industry. Due to the eutectic formation, it lowers the ...
