Current domestic production of phosphate rock used for fertilizer. As a branch of agricultural products, fertilizer production enterprises for the benefits of nature is very limited, but engage in deep processing, doing more than high-end industrial products, industrial and even earn money by foreigners, no doubt open the door for the enterprise landscape alone Good windows.
Thermal phosphoric acid production process is based on high energy consumption, high pollution, high investment of yellow phosphorus as raw materials. As energy conservation and environmental protection demanding that developed countries have implemented restrictions on the phosphorus production, Western Europe, with the wet purification of industrial phosphoric acid phosphoric acid substitution rate of heating method to date has exceeded 75%.
At the same time, the international price of yellow phosphorus has been up all night. Development and application of wet phosphoric acid purification technology, research and development production of fine chemical products as high-grade phosphate industry, the inevitable development. Sichuan University, a new solvent extraction purification of wet process phosphoric acid technology application and promotion of industrialization, no doubt to boost the momentum of development, changes in domestic phosphate fertilizer and other bulk chemical products, excess capacity, companies with low-end products to seize the international market structure.
