FROTHERS FOR MINERAL FLOTATION

The invention provides methods and compositions for improving a froth flotation type separation. The method uses a microemulsion to improve the effectiveness of a frother. The improvement allows for low dosages of frother to work as well as much greater amounts of non-microemulsified frother. L'...

Zusammenfassung:	The invention provides methods and compositions for improving a froth flotation type separation. The method uses a microemulsion to improve the effectiveness of a frother. The improvement allows for low dosages of frother to work as well as much greater amounts of non-microemulsified frother. L'invention concerne des procédés et des compositions permettant d'améliorer une séparation de type par flottation par mousse. Le procédé met en oeuvre une microémulsion pour améliorer l'efficacité d'un moussant. Cette amélioration permet de faire agir de faibles doses de moussant tout comme de beaucoup plus grandes quantités de moussant non microémulsionné.
