| titleOfInvention | Method for producing calcium fluoride from wastewater containing hydrofluoric acid, hexafluoroantimonic acid and hexafluoroaluminate |
| abstract | The invention relates to a method for producing calcium fluoride from wastewater containing hydrofluoric acid, hexafluoroantimonic acid and hexafluoroaluminate, characterized in that potassium fluoride is added to contain hydrofluoric acid, hexafluoroantimonic acid and hexafluoroaluminum. The acid waste water is assisted by a reagent such as ammonia water, calcium hydroxide, and flocculant, and is subjected to precipitation and filtration to produce calcium fluoride with good purity, and is particularly useful for treating waste LCD panel glass etching liquid to produce fluorination. calcium. |
