  • calcium chloride - Agricultural Marketing Service

    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). Potentially, this method can produce material of highest purity, and this is the
