Abstract

L'invention a pour objet un procédé de production de sels du groupe IA qui s'inscrit dans un processus de recyclage des effluents industriels contenant des composés du groupe IA et des composés de fer et/ou de zinc. Le procédé consiste à chauffer les effluents industriels dans une atmosphère réductrice; à traiter les fumées d'échappement chauffées au stade précédent avec une solution lixiviante de chlorure d'ammonium pour obtenir un précipité contenant des sels du groupe IA; et à extraire du précipité les sels du groupe IA.
