Abstract
"PROCESSO PARA A RECUPERAçãO SIMULTâNEA DE ALUMINA E SìLICA SUBSTANCIALMENTE PURAS A PARTIR DE UM ALUMINOSSILICATO". Um processo para a recuperação simultânea de alumina e sílica substancialmente puras a partir de um aluminossilicato. O processo compreende as seguintes etapas: (i) aquecer o aluminossilicato com CalCl~ 2~ hidratado para obter produtos de silicato de cálcio-alumínio e aluminato de cálcio em que o sal CaCl~ 2~ é substancialmente isento de MgCl~ 2~; (ii) lixiviar os ditos produtos com HCl para formar uma solução compreendendo AlCl~ 3~ e CaCl~ 2~ e sílica insolúvel; (iii) separar a sílica insolúvel da solução; e (iv) cristalizar AlCl~ 3~ a partir da solução e recuperar alumina a partir do AlCl~ 3~ cristalizado. O processo pode compreender ainda as seguintes etapas:(v) remover substancialmente MgCl~ 2~ a partir da solução de CaCl~ 2~ da etapa (iv); e (vi) reciclar a solução de CaCl~ 2~ para utilização na etapa (i).
