Abstract

L'invention concerne un procédé utilisant la synergie de multiples déprimants pour améliorer la dépression du sulfure de fer sans nuire à la récupération des minéraux sulfurés précieux en flottation de sulfures métalliques non ferreux, tout en réduisant ou en éliminant l'utilisation de produits chimiques posant des problèmes d'environnement, tels que les polyamines. Le procédé présente des avantages économiques et écologiques considérables. Les multiples déprimants comprennent au moins un polymère organique, au moins un composé soufré et/ou au moins un composé organique azoté.
