| Abstract: | With brine and ammonia aqueous solution as raw material, preparation of the leached type Mg(OH)_2 was studied. Effect of the temperature and time of the reaction, the aging time and temperature, and the raw material ratio on the preparation was discussed. The optimum technologic conditions were obtained based on experimental results. Under optimized conditions, the quality of the leached type Mg(OH)_2 reached the standard of HY/T111-2008, and the conversion of Mg~ 2+ in brine was up to 95%. |
