Abstract

L'invention concerne la transformation hydrométallurgique des concentrés de minerais et notamment la transformation d'un concentré de loparite; elle peut s'utiliser pour l'extraction intégrée de composés de titane, de niobium et de tantale à partir dudit concentré. Le procédé de transformation d'un concentré de loparite comprend l'attaque du concentré de loparite avec un acide minéral, la séparation des composés de titane, de niobium et de tantale puis la formation d'une solution de fluorures de titane, de niobium et de tantale au moyen de l'acide fluorhydrique. La nouveauté consiste en ce que l'attaque du concentré se fait avec de l'acide chlorhydrique, la séparation de titane, de niobium et de tantale se fait par l'extraction à partir de solutions chlorées au moyen d'un mélange organique, et les solutions fluorées de ces métaux rares sont obtenues par leur réextraction de l'extrait à l'aide de l'acide fluorhydrique concentré. L'invention permet de simplifier le processus grâce à l'élimination des stades de dissolution d'un gâteau d'hydrates dans l'acide fluorhydrique et, partant, des stades de dilution des solutions contenant du titane, du niobium et du tantale.
