With Light burned magnesium powder With the rapid growth of output and export, many constraints on the further development of China's calcined magnesium oxide industry have gradually emerged. First, due to years of almost predatory mining, the reserves of high-quality magnesium ore resources have declined rapidly, and the amount of high-quality ore mining has decreased year by year; Secondly, due to the slow technological progress, high-end magnesia products are still controlled by foreign manufacturers, especially the technology of producing high-end magnesia from low-grade magnesite has not yet made a breakthrough. With the continuous depletion of high-quality magnesite, the quality of magnesia products is declining; Third, China's magnesia production and export enterprises have been "scattered, numerous and small", and the industry order and standards are not perfect.
As a result, China's export of magnesium oxide has a long-term disadvantage of "first-class resources, second-class processing, and third class prices". More seriously, the low export price also makes Chinese export enterprises face severe anti-dumping investigations. In order to achieve sustainable development, the Chinese government has adopted a dual control policy of export quota and license for magnesium oxide, which has protected the magnesite resources and environment to a certain extent, and realized the sustainable exploitation and utilization of magnesite resources.
