Title (EN) DEPRESSANT COMPOSITIONS AND METHODS FOR DEPRESSING THE GANGUE SULFIDE MINERALS DURING THE FLOTATION OF SULFIDE ORES
(FR) COMPOSITIONS DE DÉPRIMANT ET PROCÉDÉS DE DÉPRESSION DES MINÉRAUX SULFURÉS DE GANGUE PENDANT LA FLOTTATION DE MINERAIS SULFURÉS
Abstract: front page image
(EN)Compositions including blends of one or more acrylamide/allyl thiourea polymer as a first depressant, and one or more carboxyalkyl dithiocarbamate compound as a second depressant, and their use as depressants in the beneficiation of sulfide minerals from ores and/or concentrates are disclosed herein, along with methods for selectively separating value sulfide minerals from non-value sulfide minerals in a froth flotation process for the recovery of such value minerals.
(FR)L'invention concerne des compositions comprenant des mélanges d'un ou plusieurs polymères d'acrylamide/d'allyle thiourée en tant que premier déprimant, et un ou plusieurs composés de dithiocarbamate de carboxyalkyle en tant que second déprimant, et leur utilisation en tant que déprimants dans l'enrichissement de minéraux sulfurés à partir de minerais et/ou de concentrés, ainsi que des procédés de séparation sélective de minéraux sulfurés de valeur à partir de minéraux sulfurés non de valeur dans un procédé de flottation par moussage destiné à la récupération de tels minéraux de valeur.
