| titleOfInvention | A kind of method for preparing silicon, aluminium series of products as raw material with gangue |
| abstract | The invention discloses a kind of method for preparing silicon, aluminium series of products as raw material with gangue, the method is that high-temperature fluorination roasting is carried out to gangue using gas or solid fluorinated dose, generates the fluoride and nonvolatile AlF of volatile silicon 3 , so as to realize efficiently separating for silicon and aluminium.Volatile matter is absorbed or condensed recovery, the fluosilicic acid of mass concentration 1 30% can be obtained（H 2 SiF 6 ）Or purity reaches more than 99% fluosilicate, the silicon systems product can be used directly as chemical products, it is also possible to which this is the white carbon that the neutralized precipitation method of raw material prepare that purity is up to more than 90%（SiO 2 •nH 2 O）.Product of roasting AlF after divided silicon 3 Content reaches more than 80%, can produce Al as alkaline process 2 O 3 Or electrolgtic aluminium ice crystal (3NaF AlF 3 ) and AlF 3 Raw material, the Al of preparation 2 O 3 Purity reaches more than 98%, 3NaF AlF 3 And AlF 3 Purity meets industrial goods requirement.Silicon systems and aluminium system product category prepared by the present invention are more, and purity is high, and purposes is wide. |
