China's phosphate resources ensure that the mining period is less than 20 years. Although China's phosphate reserves amounted to 13.1 billion tons, industrial reserves after deducting design losses and mining losses were only 2.1 billion tons, of which high-grade ore reserves were only 1.1 billion tons. According to China's current mode of mining for abandoning poverty, China's current guaranteed phosphate mining time is less than 20 years.
The combination of mineral phosphorus and phosphorus is the development trend of yellow phosphorus production. As China's phosphate resources ensure that the mining period is less than 20 years, the price of phosphate ore has increased by more than 200% in the past two years. Phosphorus ore is increasingly important for yellow phosphorus production. In the past two years, the tight supply of electricity caused some yellow phosphorus production plants to be forced to suspend production. In the first half of this year, Yunnan Province adopted more power limiting measures for yellow phosphorus production companies, thus ensuring that power supply also plays an important role in the stable production of yellow phosphorus enterprises. . In order to achieve the stability of production, large-scale yellow phosphorus producers have purchased phosphate ore and built their own power plants to resist the risk of raw material supply disruption.
Refinement is the development direction of phosphorus chemical industry. In the downstream products of phosphorus chemical industry, products with low added value such as sodium pentaoxide are more important. The domestic market of these products is already saturated, and it is only possible to adopt the form of export to absorb excess production capacity. For high value-added phosphorus chemical products such as toothpaste-grade calcium hydrogen phosphate, food grade and electronic grade phosphoric acid, domestic and international markets are still in short supply, and high-value-added fine-phosphorus chemical products will be the future development direction of the phosphorus chemical industry. .
Phosphate fertilizer production excess. With the rapid expansion of domestic diammonium phosphate production capacity, the new domestic diammonium production capacity will be around 5 million tons in the next two years, which has exceeded the current annual import volume of 3 million tons. The market for diammonium phosphate in China will experience excess capacity. Only those manufacturers of diammonium that combine acid fertilizers or mineral fertilizers can have more competitive advantages in the fierce market competition.
