摘要：

Introduce several examples of surface active agents used in wet-process phosphoric acid (WPPA) to show its effect on the quality of phosphogypsum. Summarized both domestic and foreign methods of comprehensive utilization of phosphogypsum, such as being made into calcium sulfate whisker, building materials, soil improvement agent, chemical raw materials and etc. Some problems of resources utilization of phosphogypsum in China are summarized, and reasonable suggestions are put forward.
