Abstract
Il est décrit des procédés de production dalumine métallurgique comprenant lextraction de matières brutes qui contiennent de laluminium avec de lacide chlorhydrique représenté par une liqueur résiduaire acide, la séparation du liquide chargé de chlorure formé dans une silice précipitée de déchets et dans une liqueur de chlorure éclaircie, et la cristallisation dhexahydrate de chlorure daluminium à partir de la liqueur de chlorure éclaircie, la calcination pour produire une alumine brute, le lessivage dalumine brute avec une liqueur résiduaire dalcaline, et la précipitation dune liqueur daluminate qui en découle, le lavage deau, et la calcination subséquente de lhydroxyde daluminium séparé. Environ 15,0 % de la liqueur résiduaire acide est soumise à la pyrohydrolyse, la concentration dion chlorure dans lalumine brute est maintenue entre 0,2 % et 5,0 %, la concentration dion chlorure dans la liqueur résiduaire dalcaline est maintenue entre 40 et 90 grammes par litre, et entre 10,0 % et 40,0 % massique de la liqueur résiduaire dalcaline est concentrée jusquà ce que les cristaux de composé contenant du chlore soient séparés. Le résultat technique est une meilleure qualité dalumine et une consommation énergétique réduite dans la production dalumine métallurgique de matières brutes de qualité inférieure.
