Title (EN) SULFONATED MODIFIERS FOR FROTH FLOTATION
(FR) MODIFICATEURS SULFONÉS POUR FLOTTATION PAR MOUSSE
Abstract:
(EN) Improved sparge compositions for reverse froth flotation separation and uses thereof, and methods of reverse froth flotation are described. The sparge compositions comprise sulfonated polymeric modifiers which can act as dispersants and depressants, and the compositions are suitably used in the reverse froth flotation of particulate material containing ultrafine particles. For example, the compositions and methods can be used in the separation of phosphate beneficiary from ores comprising phosphates, dolomite, calcite, clay, silica, silicates, carbonates, and mixtures thereof.
(FR) L'invention porte sur des compositions de lavage améliorées pour la séparation par flottation par mousse inverse et sur leurs utilisations, et sur des procédés de flottation par mousse inverse. Les compositions de lavage comprennent des modificateurs polymères sulfonés qui peuvent agir comme dispersants et inhibiteurs, et les compositions sont utilisées de manière appropriée dans la flottation par mousse inverse d'un matériau particulaire contenant des particules ultrafines. Par exemple, les compositions et les procédés peuvent être utilisés dans la séparation d'une fraction enrichie en phosphate à partir de minerais comprenant des phosphates, de la dolomite, de la calcite, de l'argile, de la silice, des silicates, des carbonates et des mélanges de ces derniers.
