| Abstract: | The utilization status of fluorine resource in phosphate fertilizer production of China is analyzed, a low cost process for achieving ammonium fluosilicate from fluorinated tail gas of phosphate fertilizer production, and the operation status of pilot plant are introduced. The test results show that： the removal rate of fluorine is high, the product quality of ammonium fluosilicate is better than the national standard, the manufacturing cost of series fluorine salt products is lower than that with the existing technical route. The process with short flow, high yield of fluorine, low cost, is suitable for the technical renovation of the existing phosphate fertilizer enterprise. |
