| titleOfInvention | A process of extracting sodium bicarbonate and other salts contained in natural soda bicarbonated mineral waters |
| abstract | Sodium bicarbonate associated with a small quantity of other soluble salts is extracted from natural soda bicarbonated mineral waters by a three-stage process consisting in heating to at least 80 DEG C. in order to remove carbon dioxide, and separating the calcium carbonate precipitated, concentrating, and finally precipitating sodium bicarbonate by passing carbon dioxide, preferably under pressure. The mother liquor adhering to the crystals after their removal is allowed to evaporate and contains soluble salts other than the bicarbonate. The carbon dioxide evolved in the first operation may be utilized in the subsequent step of carbonating the liquor. |
