Abstract: The globe current status of production technology of feed grade phosphate，including distribution production ca- pacity，and major producers，were introduced.The defluorination technologies（including concentration stripping defluorina- tion and precipitation defluorination technology of phosphoric acid by wet process and diluted acid precipitation defluorina- tion technology of phosphoric acid by wet process） in the production technology of feed grade phosphate were introduced em- phatically.The production technologies of various feed grade phosphates，such as monocalcium phosphate(MCP)，mono-dicalcium phosphate（MDCP），dicalcium phosphate（DCP），and deflurized tricalcium phosphate（DFP/TCP），were also described in detail.The sustainable development trend of feed-grade phosphate production technology was analyzed at last.

Key words: feed-grade phosphate, phosphoric acid by wet process, defluorination
