CA 2539830

The invention concerns a method for processing heavy metal-laden spent sulfuric acid. For this, iron-laden spent sulfuric acid or iron-laden sulfuric materials obtained therefrom are reacted with a material that contains iron chloride and optionally other metal chlorides, producing iron (II) sulfate. The spent sulfuric acid preferably derives from titanium dioxide production.

Cette invention concerne un procédé de traitement d'acide sulfurique épuisé chargé de métaux lourds. Ce procédé consiste à faire réagir de l'acide sulfurique épuisé chargé de fer ou des matériaux sulfuriques chargés de fer obtenus à partir de cet acide avec un matériau qui contient du chlorure de fer et éventuellement d'autres chlorures métalliques, ce qui produit du sulfate de fer (II). L'acide sulfurique épuisé est de préférence issu de la production de dioxyde de titane.
