Interfacial Tension between Smelting Slag and Matte in Jinchuan Nickel Flash Furnace

Surface tensions of slag and matte in Jinchuan nickel flash smelting process were respectively calculated by the way of Butler equation and polynomial fit. Based on Girifalco-Good equation interfacial ten- sions between slag and matte were calculated. The relationship between interfacial tension and slag composi- tion、surface tension as well as temperature was discussed. Some advice for decreasing the noble metal loss in Jinchuan nickel flash smelting process slags was given.
