It was learned from the Science and Technology Department of Guizhou Province that it was organized and reported by the Science and Technology Department of Guizhou Province, including the key projects of the “Eleventh Five-Year” National Science and Technology Support Plan of Guizhou Major Phosphorus Mining Group and related research institutes within and outside the province. The research on the key technologies for efficient development and utilization of phosphate resources and deep processing has recently passed the acceptance by the expert group of the Ministry of Science and Technology.

According to briefings, this project has focused on the characteristics of China's phosphate rock resources, and carried out research and research in 10 areas focusing on common technical difficulties in the areas of efficient development and utilization of phosphate resources, phosphorus fine chemicals, phosphorite associated resources, and comprehensive waste utilization. . The total investment of the project is 2.029 billion yuan, and 63.30 million yuan has been invested by the national science and technology support program. Since 2007, Guizhou Province has obtained the largest amount of state-funded science and technology projects.

It is understood that under the close cooperation and joint research of scientific research institutes and related enterprises, through the independent innovation and technology integration, 26 domestic achievements were converted and applied, more than 40 key technologies were broken, 96 domestic patents were applied, and domestic patents were granted. 25 items. Based on the research results of the project, the world’s largest 100,000-ton/year wet-process phosphoric acid purification plant and the world's first 20,000-ton/year anhydrous hydrogen fluoride plant with associated phosphate iodine resources as raw materials have been built. At the same time, a series of papers were published and a group of talents were trained. The implementation of this project is the key to the selection of phosphate resources in China, the deep processing of phosphorus fine chemical products and the development of the phosphorus chemical industry chain, and the establishment of a circular economy.

Guizhou boasts large total phosphorus resources and low development costs. It has good conditions for making large and strong phosphorus chemicals. Among them, Yanfu Phosphorus Mine has been established as a leading company in China's phosphorus chemical industry. The comprehensive utilization technologies and talents of phosphorus mining and phosphate chemical industry formed through the implementation of this project will solve the technical difficulties in restricting the development of complex and difficult-to-process phosphate ore resources that account for half of the total phosphorus resources in Guizhou, and provide a sustainable development for the Guizhou phosphate industry.
