Abstract 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. 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 los minerales de valor.
