| titleOfInvention | A kind of method of sulfuric acid process phosphoric acid by wet process efficient impurity removal |
| abstract | The present invention relates to a kind of methods of sulfuric acid process phosphoric acid by wet process efficient impurity removal, one or more of calcic inorganic matter, inorganic matter containing aluminium, siliceous inorganic matter, sulfur-bearing inorganic matter or fluorine-containing inorganic matter are added in sulfuric acid process phosphoric acid by wet process, the molar ratio for adjusting Ca, Al, Si, S, F in sulfuric acid process phosphoric acid by wet process is (3.8-12): (0.8-1.2): (1-1.20): (1-1.20): (12-15), it is reacted, makes Ca, Al, Si, S, F impurity element in sulfuric acid process phosphoric acid by wet process with Ca 4 AlSiSO 4 F 13 ·12H 2 The form of O is precipitated out, to reach purification purpose.Compared with prior art, the present invention once removes five kinds of impurity elements in phosphoric acid by wet process by changing phosphoric acid by wet process ingredient, makes the major impurity element in phosphoric acid by wet process with compound Ca 4 AlSiSO 4 F 13 ·12H 2 The form of O is precipitated out, to realize the purpose of wet phosphoric acid purifying. |
