Abstract
PROCESSO SEMISSECO OTIMIZADO PARA SINTERIZAÇÃO DE ALUMINOSSILICATOS NA PRODUÇÃO DE ALUMINA. A invenção se refere a um aparelho para tratamento de alumínio compreendendo pelo menos um dispositivo para misturar (20, 22, 30, 40) minério de alumínio com calcário e carbonato de sódio e/ou potássio para obter uma mistura e um reator de calcinação (60) para produzir a calcina. Um reator de leito fluidizado circulante (50) está disposto entre o dispositivo para misturar (20, 22, 30, 40) e o reator de calcinação (60) e no qual a mistura é pré-calcinadaOPTIMIZED SEMI-DRY PROCESS FOR SINTERIZING ALUMINOSILICATES IN ALUMINA PRODUCTION. The invention relates to an apparatus for treating aluminum comprising at least one device for mixing (20, 22, 30, 40) aluminum ore with limestone and sodium and/or potassium carbonate to obtain a mixture and a calcination reactor ( 60) to produce calcine. A circulating fluidized bed reactor (50) is arranged between the mixing device (20, 22, 30, 40) and the calcining reactor (60) and in which the mixture is pre-calcined.
