According to Wu Xiyan, chairman of the China Phosphate Fertilizer Association, the comprehensive utilization of phosphogypsum in China began in the early 1990s. For more than a decade, with the rapid development of high-concentration phosphate and compound fertilizer in China, many companies have paid more attention to the comprehensive utilization of phosphogypsum. In 1990, Shandong Lubei Group built a set of 30,000 tons of ammonium phosphate - 40,000 tons of sulfuric acid - 60,000 tons of cement project, and later built 300,000 tons of ammonium phosphate - 400,000 tons of sulfuric acid - 600,000 tons of cement project. This is the world's largest industrial plant for the production of co-production of sulphophosphoric acid and cement. This device not only consumes all of the company's phosphogypsum, but also requires a portion of phosphogypsum from nearby companies to supplement it. For more than a decade, Tonghua Group has used a variety of calcining devices to produce β-semi-hydrated gypsum, namely building gypsum, cement retarder and other products. Huasheng Co., Ltd. cooperates with Shandong Taihe Group to produce gypsum plasterboard. The products sell well in the northeast region and also produce cement retarder. The two companies, Guizhou Hongfu and Kaifeng Phosphorus, use phosphogypsum to produce cement retarders, gypsum blocks, gypsum bricks and fills in mine gobs. At present, Hongfu, Kaifeng and Lubei have been listed as the national circular economy pilot units by the National Development and Reform Commission and the State Environmental Protection Administration.
It is also known that the best comprehensive utilization of phosphogypsum in the world is Japan. Japan's natural gypsum has very little reserves and is of poor quality, so the enthusiasm for using the by-product phosphogypsum is high. As early as 1931, Nissan Chemical Co., Ltd. first used gypsum board made of phosphogypsum, and in 1956 it started to use it as a cement retarder. Phosphogypsum produced by wet production of phosphoric acid is used in Japan. There is a phosphate fertilizer plant in Belgium, and most of the phosphogypsum is used; Finland uses some of Kaimira phosphogypsum to produce wood fiber gypsum board; Britain, France and other countries also do a lot of work in the use of phosphogypsum to produce new building materials. Major phosphate producers in the United States, Morocco, Tunisia, and Jordan have high levels of radioactive phosphogypsum, most of which are stored and disposed of, while Egypt and other countries directly discharge it into the sea.
Recently, a special forum on comprehensive utilization of phosphogypsum issued a message. At present, the comprehensive utilization rate of phosphogypsum in China is less than 10%, and it is still in its infancy.
