Recovery enhancement of gold and silver in chalcopyrite flotation "Bucim" - Macedonia applying new collectors

The generally concept of the new investigated technological schemes and reagent regimes of the flotation concentration process in the Bucim copper mine is based both firstly the demands of the possible complex recovery from useful present minerals or mineral components: CuFeS2, FeS2, Fe3O4, Fe2O3, Na - feldspar, K - feldspar, SiO2 and secondly increased recovery of the gold and silver. These laboratory and industrial scale tests have enabled to prove the optimum conditions and reagent regime of the new collectors application by means of: ORFOM C0800 product from PHILLIPS CHEMICAL COMPANY and PENFLOT-3 product from MERKS COMPANY. In this paper will be shown the compare of the applied standard operating conditions and new operating conditions, specially in industrial scale
