Abstract

Lixiviation en continu de minerais. On stratifie en continu plusieurs couches unitaires le minerai pulvérisé et on en asperge uniformément les surfaces planes avec un minimum d'acide, d'alcali ou de solvant organique; on maintient ainsi une concentration élevée en solvant dans le minerai, on accumule la chaleur que produit la réaction exothermique par contact entre le solvant, le minerai et l'eau, et on l'utilise pour la maturation thermique du minerai. Application particulière : traitement des minerais d'uranium.
