China is one of the three largest exporters of magnesia in the world. The annual output of low-iron magnesia exceeds 25Mt, but the main products are those with purity less than 95%, while the output of high-purity magnesia (with mass fraction of MgO > 99%) is very small. The annual production capacity is less than 0.4Mt, which can not meet the annual domestic demand of 1Mt. Most of them rely on imports. It can be seen from this that the gap of magnesium oxide in China is very large and has great development potential.
60% of the magnesium products produced in the United States come from brine, followed by magnesite and dolomite. The method of production is calcining magnesia or magnesite from brine, which is causticized by lime, and then further processing of functional magnesia according to different uses. The total production capacity of calcined magnesia is 1.1-1.2 Mt/a, and the light magnesia is less than 300 kt/a. In Western Europe, 70% of magnesium oxide is made from magnesite and dolomite. The total amount of magnesium oxide is 1.5-1.6Mt/a, and less than 25% of light magnesium oxide products. Magnesium oxide in Eastern Europe is mainly made from calcined magnesite, more than 90% of which is of refractory grade. In Africa and the Middle East, magnesium oxide is mainly produced from seawater or natural minerals. The production capacity is 400 Kt/a, and the light magnesium oxide production is very small. Japan is the largest producer of magnesium oxide in Asia. Its production capacity is more than 300 k/a. The main production is calcined magnesium oxide in alkaline solution. 70-80% of refractory magnesium oxide is imported.
