Abstract

processos para a recuperação de rutilo sintético de altograu a partir de minérios de baixo grau a presente invenção refere-se, em primeiro lugar, a um processo de lixiviação em duas fases utilizando ácido clorídrico concentrado em que o minério moído é lixiviado com duas quantidades separadas de ácido clorídrico em temperaturas diferentes. em segundo lugar, a invenção refere-se a um processo de lixiviação em uma etapa usando hcl concentrado e uma razão fixa de ácido para minério para prevenir a hidrólise de titânio. depois disso, o titânio dissolvido é precipitado a partir do licor de filtro por hidrólise e os cloretos de ferro ainda solúveis são então opcionalmente submetidos à oxi-hidrólise para recuperar o óxido de ferro e hcl. o processo foi desenvolvido para minérios de baixo grau (menos de 12% tio2), e pode, naturalmente, ser aplicado vantajosamente para os minérios contendo titânio de graus mais altos, que aprimora uma variedade de minérios de titânio-ferro de qualidade inferior em concentrado de titânio de alta qualidade e produtos de óxido de ferro.
