Magnesium is an important strategic resource. Other countries can only rely on our country to export when their own reserves are small. However, while enjoying this advantage, we should pay attention to the protection and utilization of magnesia resources.
The scarcity of resources determines that countries must implement sustainable development strategies. Scarcity of resources and sustainable development provide a theoretical basis for China's implementation of magnesia export quota control policies. With the rapid growth of China's magnesia production, the reserves of medium-quality magnesia resources are also rapidly declining. Although China's magnesite resources are still very rich, with the large-scale mining over the years, the number of medium-grade ore has decreased year by year, and the quality of magnesia has also declined.
