Flotation of gold and goldbearing 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

Extremely Fine Gold Recovery Gold Recovery Methods

Apr 14, 2015 · Flotation is not a good method for fine gold recovery. Gold is dense and its ability to be floated is only fair. Flotation of gold has been done in laboratories, but it is not a commercially used method because of the difficulties involved, there are many methods of fine gold recovery which are better than flotation.

Rcovery of gold in pyritic ores mineengineer

Recovery of gold in sulfide ores has fallen into several egories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery.
