| titleOfInvention | Method for preparing high purity water soluble calcium using crystallization |
| abstract | The present invention relates to a method for producing high purity water-soluble calcium using a crystallization method, the composition of which is 30-50 ml / l of ammonia water (NH 4 OH) or 40-ammonia gas (NH 3 ) while stirring the calcium chloride aqueous solution from which suspended matter is removed. Adding 60 ml / l to remove impurities of Sr, K and Na; Heating the aqueous solution from which the impurities are removed to produce a concentrated solution, and growing the single crystal by the slow cooling method and the temperature difference method; Producing a calcium carbonate slurry of high purity by gas blowing the grown crystals; Filtering and drying the resulting calcium carbonate slurry.n n n n Calcium chloride, crystallization method, calcium carbonate powder, organic acid solvent |
