Abstract

L'invention se rapporte à un procédé réalisable à l'échelle industrielle, permettant de valoriser des matériaux titanifères. Ce procédé comprend les étapes suivantes: (i) un prétraitement visant à prédisposer la silice à un lessivage ultérieur soumis à des conditions particulières, et (ii) un lessivage aqueux en présence d'un acide, dont les conditions sont choisies de façon que la silice formant une solution ne soit ni hydrolysée, ni précipitée sous forme d'un silicate. L'étape de prétraitement (i) peut comprendre un lessivage alcalin, la calcination ou la fonte. L'étape de lessivage (ii) peut être effectuée avec des matières solides de faible masse volumique.
