Title (EN) MINERAL ORE FLOTATION AID
(FR) AUXILIAIRE DE FLOTTATION POUR MINERAI
Abstract: front page image
(EN)A process is provided for the selective separation of ore values when a ground mineral ore containing gangue material is first dispersed in an aqueous medium and thereafter conditioned with an effective amount of a treatment reagent whereby the recovery of valuable materials from a froth flotation process is increased. In an embodiment of the present invention, the treatment reagent is a water soluble ethylene oxide/propylene oxide polymer.
(FR)La présente invention concerne un procédé de séparation sélective de minerais de valeur, dans lequel un minerai contenant une matière de gangue est dispersé dans un milieu aqueux, puis conditionné à l'aide d'une quantité efficace d'un réactif de traitement. Ce procédé permet d'accroître le taux de matières précieuses extraites à partir d'un processus de flottation par moussage. Dans un mode de réalisation de l'invention, le réactif de traitement est un polymère d'oxyde d'éthylène/d'oxyde de propylène soluble dans l'eau.
