Abstract:

China′s comprehensive utilization of phosphogypsum has ranked the world′s leading level,and the comprehensive utilization approaches are diversified, but there are also some problems to be solved,such as unclear understanding of phospho-gypsum,lack of innovation motivation,lack of coordination between upstream and downstream industries and so on.The im-plementation of “carbon peak and neutrality goals” strategy is both an opportunity and a challenge for the comprehensive utiliza-tion of phosphogypsum resources. Based on this,the current situation of comprehensive utilization of phosphogypsum resources at home and abroad was introduced, the production and utilization of phosphogypsum in China were mainly described.With the improvement of China′s phosphate fertilizer production process, technology and management level,the quality of phosphogypsum is gradually improved,the amount of phosphogypsum by-product of phosphate fertilizer is gradually reduced,and the comprehensive utilization of phosphogypsum resources and the level of utilization will continue to improve.

Key words: phosphogypsum, comprehensive utilization of resources, current situation, existing problems, development trend
