needed for the production of heavy calcium carbonate stainless
the production of heavy calcium carbonate stainless those Calcium chloride is produced industrially by at least three methods. In one process, hydrochloric acid is added to calcium carbonate, producing calcium chloride and carbonic acid: CaCO. 3 + 2HCl Æ CaCl2 + H2CO3. This is a synthetic process Krohn et al., 1987 .
