HMC can be further refined through roasting, hydrolysis and other processes to produce higher value materials such as high purity hydrated magnesium carbonate, caustic calcined magnesia, hard burned magnesia, and magnesium di-hydroxide powders.
These materials are currently used in a range of high-value applications, including chemically-toughened glass, flame retardants, fertilisers, and a wide range of other products.
