In separation of copper minerals from arsenopyrite, reagents with high selectivity, but low hydrophobic property do not permit to achieve required copper recovery even at high consumptions. This is explained in the first place by notable increase of circulating loads in feed of recleaning circuits.

The poor liberation of copperarsenic minerals and copper minerals makes selectivity difficult and fine grinding is conductive for the liberation and differential flotation. The FSF slag also contains a trace amount of iron arsenide, disseminating finely and existing in the form of microgranular inclusions that occur in matte and arsenic copper alloys, or distributing edgeways. Arsenic
