Abstract

En el presente documento se describen composiciones que incluyen mezclas de uno o más polímeros de acrilamida/alil tiourea como primer depresor, y uno o más compuestos de ditiocarbamato de carboxialquilo como segundo depresor, y su uso como depresores en la beneficiación de minerales de sulfuro a partir de menas y/o concentrados, junto con métodos para separar selectivamente minerales de sulfuro de valor de minerales de sulfuro sin valor en un proceso de flotación por espuma para la recuperación de dichos minerales de valor.
