Title: METHOD FOR PREPARING HIGH-PURITY MAGNESIUM HYDROXIDE
Abstract:
The present invention relates to a method for preparing high-purity magnesium hydroxide (Mg(OH)2) and, more specifically, to a method for preparing high-purity magnesium hydroxide together with the preparation of hydrated magnesium carbonate (HMC) from a raw material solution containing calcium, magnesium, and sodium. According to the present invention, magnesium hydroxide with a high purity of 99.5% or higher, together with the preparation of hydrated magnesium carbonate, can be prepared from a raw material solution containing magnesium and sodium, thereby creating high-added values of resources.
