Representatives from the Ministry of industry and information technology, the Ministry of agriculture, the Ministry of science and technology, the Ministry of environmental protection, the Ministry of water resources, the development research center of the State Council, the petroleum and Chemical Planning Institute, the Chinese Academy of Sciences, Tsinghua University, China Agricultural University, and China Chemical newspaper attended the seminar. Experts attending the meeting believed that in the face of the industry bottleneck problems such as the lack of phosphorus rich resources, low technology of medium and low grade phosphate rock, low added value of products, and lack of phosphogypsum utilization technology, phosphorus chemical enterprises should increase investment in science and technology, extend the industrial chain, and improve the utilization rate of phosphorus resources and added value of products; The government and management departments should formulate policies to guide enterprises to carry out fine processing of products to reduce the environmental pollution caused by phosphorus slag and phosphogypsum. At the same time, we should also actively cultivate large-scale demonstration enterprises of comprehensive utilization of phosphorus resources and development of circular economy, such as Jinzhengda nuotel company.
Gao Yongfeng, deputy chief engineer of the petroleum and Chemical Planning Institute, said that the structural adjustment of the phosphorus and compound fertilizer industry should improve the R & D strength and industrialization capacity of new products and technologies, and improve the comprehensive utilization of phosphorus resources and the level of environmental safety.
Wan Lianbu, chairman of Jin Zhengda Group, said that Jin Zhengda's Exploration on phosphorus resources technology in recent years fully proved that the comprehensive utilization of phosphorus resources and circular economy are the optimal mode to realize the optimal allocation of phosphorus resources and the maximization of resource benefits in China, and also the best choice for the sustainable development of phosphorus mining and phosphorus chemical enterprises.
Song Guofa, deputy general manager of the company, said that in recent years, the company has built a circular economy industrial chain with upstream and downstream integration. In the comprehensive utilization technology of phosphogypsum, a number of domestic original and international leading new technologies and new processes are adopted, such as "graded utilization" of wet process phosphoric acid to produce water-soluble fertilizer technology, nitric acid decomposition of medium and low-grade phosphate rock to produce nitro compound fertilizer technology, phosphogypsum acid co production of cement and alkaline fertilizer technology, etc., which optimize and integrate the technological processes in each link of the phosphorus resource industry chain The problems of storage, land occupation and pollution of phosphogypsum make rational use of resources, alleviate the contradiction of sulfur resource shortage in China, and realize the comprehensive utilization of phosphate rock and its associated resources.
Cui Xuejun, President of China chemical industry news, said that the new way of producing acid and alkaline fertilizer from phosphogypsum explored by Jinzhengda Weng'an base has brought great hope for solving the problem of phosphogypsum slag yard.
