| titleOfInvention | The technique that a kind of hydrochloric acid method produces aluminium oxide |
| abstract | The invention belongs to extract aluminum oxide technology field, concretely disclose a kind of hydrochloric acid method and produce the technique of aluminium oxide, its preparation technology is: aluminum-containing mineral enters acid digestion series with mixed in hydrochloric acid after broken, ore grinding；Carrying out acid sludge separation after acid is molten, obtain acid sludge and the thick liquid of aluminum chloride, acid sludge send stockyard to store up after washing, obtains aluminum chloride seminal fluid after aluminum chloride thick liquid fine straining；Aluminum chloride seminal fluid, after evaporation and concentration, enters aluminum chloride acid out system；The aluminum chloride crystals that acid out obtains, through separating, washing, send aluminum chloride calcination system；Aluminum chloride crystals obtains alumina product after calcining.This technique is particularly well-suited to the technique that the acid system of the non-bauxitic resources such as flyash, high-silica diaspore ore, nepheline, clay, Kaolin produces aluminium oxide, prepared aluminium oxide reaches or is better than national standard metallurgical-grade aluminum oxide primes, fully meets the requirement of electrolytic aluminium. |
