Abstract

L'INVENTION CONCERNE UN PROCEDE POUR DESHYDRATER UNE SUSPENSION MINERALE AQUEUSE, QUI COMPREND L'INTRODUCTION DANS LA SUSPENSION D'UN SYSTEME FLOCULANT COMPREANT UN FLOCULANT POLYMETRE SENSIBLEMENT NON IONIQUE ET UN FLOCULANT POLYMERE ANIONIQUE. LE PROCEDE EST CARACTERISE EN CE QUE LE FLOCULANT POLYMERE SENSIBLEMENT NON IONIQUE EST AJOUTE A LA SUSPENSION AVANT L'ADDITION DU FLOCULANT POLYMERE ANIONIQUE. L'INVENTION S'APPLIQUE NOTAMMENT A LA DESHYDRATATION DE SUSPENSIONS DE KAOLIN, D'ARGILES GONFLANTES, DE CARBONATE DE CALCIUM, DE BIOXYDE DE TITANE, DE RESIDUS DE CHARBON, DE BOUE ROUGE, DE BOUES PHOSPHATEES, ETC.
