Abstract

Ledit appareil comprend des moyens (10, 12, 14) pour mélanger des poussières de four à de l'eau, afin de former une boue (16) renfermant des solides non dissous et une solution de composés solubles desdites poussières. Des moyens (18, 20, 24, 26) permettent d'introduire un flux gazeux dans ladite boue. Une pompe (32) achemine cette boue (16) d'une cuve de traitement (12) à une cuve de décantation (34), dans laquelle ladite boue est séparée en des solides évacués (38) de la base de la cuve (34), et en du liquide demeurant dans la partie supérieure de cette cuve (34).
