Abstract

La présente invention concerne un procédé et un système permettant de récupérer du dioxyde de titane et d'autres métaux de valeur à partir d'un corps solide contenant du titane. Le procédé comprend les étapes consistant à : (a) lixivier le corps solide dans de l'acide hydrochlorique pour produire un lixiviat comprenant des corps solides non dissous et une solution de lixiviation comprenant le dioxyde de titane et les métaux de valeur, la concentration d'acide hydrochlorique étant maintenue supérieure à une valeur requise pour maintenir le dioxyde de titane et les métaux de valeur dissous dans la solution de lixiviation sous pression atmosphérique; (b) séparer le lixiviat en la solution de lixiviation et les corps solides non dissous; et (c) réduire la concentration d'acide chlorhydrique dans la solution de lixiviation pour récupérer du dioxyde de titane par hydrolyse et précipitation afin de produire un liquide chargé en dioxyde de titane. Dans un mode de réalisation préféré, l'acide chlorhydrique est récupéré au moyen d'une solution de matrice.
