| Abstract: | With the industrial waste slag calcium chloride and CO 2 as the main raw materials, appropriate technologies are employed for the refining of the calcium chloride solution and CO 2 purification, and under the condition of basic calcium chloride solution, high purity ultrafine calcium carbonate is prepared by atomization and carbonation, with ammonium chloride as byproduct. The calcium carbonate is over 99% pure and over 97% in whiteness, and contains traces of magnesium, calcium and chlorine, in conformity to the requirement for the production of precision and electronic grade ceramics, also to be used in the food, pharmaceutical and household chemical industries, with remarkable economic and social benefits |
