Imeri et al.kiln by 10% and quantity of Ni by 0.0011 t Ni / tDO, decreasing production cost of Ni by 80.3 US $/ t Ni. Has been decreased realising of CO 2 ingases of rotary kiln by 17.41 m 3 NCO 2 /t DO andCO 2 in gases of electric furnace by 11.605m 3 NCO 2 /t DO.Increasing quantity of Fe total in electric furnaceslag by 3.89%, have been created satisfactorycondition, that by decreasing of acidity ofelectric furnace slag , to decrease the smeltingpoint of it and in such case to have atechnological process so equilibrium in electricfurnace, with continuous flow of slag(approximately is preserved condition :FeO + MgO + CaO = 36.78 %.If we would operate without Albanian ores, wewould have these parameters:FeO + MgO + CaO = 32.87 % .The recovery of Ni has been reached 88% in July2010.5. CONCLUSIONSIndustrial investigation has been done atsmelting complex of Newco Ferroniceli Complexin Drenas. By industrial experiments has beenproved, that nickel oxide ores could be treatedwithout difficulty in metallurgical process ofobtaining Fe-Ni, with out Limstone, by adding ofAlbanian ores, increasing remarkably productioncapacity of Fe-Ni and decreasing of productioncost as well.
