Abstract

Des solutions aqueuses d'acide chlorhydrique contenant comme composant principal du chlorure ferreux (FeCL2) dissous et provenant de divers traitements, sont libérées simultanement de leur teneur en fer et en acide silicique par précipitation du fer, d'abord sous forme d'hydroxyde ferreux Fe(OH)2, des solutions neutralisées avec de la ferraille, le précipité étant ensuite oxydé par oxydation électrolytique effectuée dans une cellule électrolytique à courant continu, munie d'électrodes insolubles et dépourvue de diaphragme, et puis soumis à un traitement de maturation effectué sous agitation, éventuellement avec addition d'un floculant.
