Abstract

Patente de Invenção de "PROCESSO INDUSTRIALMENTE REALISTA PARA O BENEFICIAMENTO DE MATERIAIS TITANìFEROS". Expõe-se um processo industrialmente realista para o beneficiamento de materiais titaníferos. O processo compreende as seguintes etapas: (i) um pré-tratamento que tem o efeito de tornar a sílica suscetível a lixiviação sob as conduções particulares de uma lixiviação subsequente, e (ii) uma lixiviação aquosa na presença de um ácido, cujas condições são selecionadas de maneira tal que a sílica que ingressa na solução não é hidrolisada ou precipitada como um silicato. A etapa de pré-tratamento (i) pode compreende lixiviação alcalina, ustulação ou fusão. A etapa de lixiviação (ii) poderá ser realizada sob baixas densidades de sólidos.Invention Patent of "INDUSTRIALLY REALISTIC PROCESS FOR THE BENEFIT OF TITANIFER MATERIALS". An industrially realistic process is exposed for the processing of titaniferous materials. The process comprises the following steps: (i) a pre-treatment that has the effect of making the silica susceptible to leaching under the particular conducts of a subsequent leaching, and (ii) an aqueous leaching in the presence of an acid, the conditions of which are selected in such a way that the silica entering the solution is not hydrolyzed or precipitated as a silicate. The pretreatment step (i) can comprise alkaline leaching, roasting or melting. The leaching step (ii) can be performed under low density of solids.
