Investigations on influence of aqueous emulsion of n–dodecane on flotation of sulfides and organic–carbon–containing shale from Legnica–Glogow Copper Basin (LGOM, Poland) are presented in the paper. Seven flotation experiments were conducted. Each flotation feed consisted of dolomite, quartz and one of following components: chalcopyrite, chalcocite, bornite, covellite, galena and shale containing organic carbon. The results indicate that chalcopyrite, bornite, covellite and shale float well in the presence of 200 g/Mg of n–dodecane and in a short period of time. Chalcocite and galena do not float with n–dodecane, even when the dose of the nonpolar collector for chalcocite flotation is increased. The studies explain a selective influence of the nonpolar collector on flotation of the copper sulfides ore from LGOM.
