This study focuses on the basic reaction mechanism, reaction conditions, properties of reaction products and analysis methods for the preparation of magnesium hydroxide by this method. Through experimental exploration, the ratio of ammonia and lime was optimized, the appropriate reaction temperature and reaction time were determined, a complete separation and extraction process was established, and the stability and performance of the extracted magnesium hydroxide were tested. The results showed that the ammonia-lime brine method can efficiently prepare high-purity and high-quality magnesium hydroxide, which has excellent stability and a mature formula and can be used in industrial production.
