The result is higher purity grades and solids concentration than traditional mined magnesite ores, increased yield, considerably lower cost per unit of weight use and minimal to negligible by-products contribution in industrial applications. The HMC can then be further processed, producing high purity magnesium oxides. High purity grades are particularly important for food, pharmaceutical, personal care and animal health applications.The process relies on the selective removal of calcium by precipitation, then subsequent precipitation of magnesium to produce high purity hydrated magnesium carbonate (HMC).
