  • Flotation of gold and gold-bearing ores - ScienceDirect

    Very few gold flotation plants use single collectors and the preference is either to add a blended collector, that is, a mixture of a number of collectors, or collectors added separately in smaller quantities than those of the primary collector. These collector combinations result in better overall flotation
