Abstract
Disclosed herein is a process for preparing a high-purity magnesium carbonate by mixing magnesium oxide and carbon dioxide in a reactor under optimum supercritical reaction temperature and pressure. According to the process, a high-purity magnesium carbonate can be prepared efficiently by satisfying the supercritical reaction conditions, which are easily accomplished by using the internal pressure of a liquid carbon dioxide container for supplying carbon dioxide to the reactor without using a gas booster and a supercritical pump. Therefore, the process can minimize equipment investment costs and energy consumption.
