| titleOfInvention | The dry method process for calcining of low alumina-silicon ratio alumyte |
| abstract | The present invention proposes a kind of dry method process for calcining of low alumina-silicon ratio alumyte, including step：Dispensing, mixing are carried out with agstone, bauxite powder, the circulation alkali liquor of soda ash and evaporation later, it is sintered into rotary kiln, it is levigate after sintered clinker cooling, chamotte powder plus adjustment liquid are subjected to dissolution, the slag that chamotte powder dissolution is obtained is carried out after 5~7 reverse fully washings, washing lotion is stored up as adjustment liquid, slag；The solution that chamotte powder dissolution is obtained and desiliconization after sodium aluminate crystallization mixed dissolution, then carry out kind of a point decomposition, and seed precipitation solution is carried out in two steps evaporation and salt discharge.Method proposed by the present invention, for the bauxite of low alumina -silica ratio, appropriate lime stone and soda ash is equipped with raw materials for sintering, the chamotte powder after sintering is effectively leached；Dry method firing condition is controlled, sintering process technological process is reduced more than 1/3rd, corrosion brings up to more than 90%, and the overall recovery of aluminum oxide reaches more than 90%. |
