China is the world's largest exporter of magnesium, but the main export products are still low value-added primary raw materials magnesium ingots. Magnesium exports to the Netherlands, Japan, the United States, Canada, Italy and Germany and more than 50 countries and regions. China is a large producer of magnesium, and magnesium is rich in magnesium resources, accounting for 22.5% of the world's total reserves. The total reserves of magnesite are 2.7 billion tons and dolomite ore is more than 4 billion tons. The reserves of potassium and magnesium salts in Qinghai Province and coastal halogen are very large. The total amount of magnesite resources in China is 31.45 billion tons, and the one or two grade ore that meets the requirements of magnesium smelting accounts for 78%. Low investment cost, abundant coal resources, low cost raw material supply, and abundant labor force advantages all make magnesium production in China have a good economy and competitiveness. China's original magnesium production accounts for 40% of global output, and is the world's largest producer and exporter of magnesium.
