Abstract: The interfacial tension between FeO-CaO-SiO_2-MgO system slag and Cu-Fe-S system matte was determinated by the X-ray radiograph sessile drop method.The effects of FeO/SiO_2 ratio in the slag,contents of CaO,FeO,ZnO and CaF_2 in the slag on interracial tension and the relation of inter facial tension with the grade of matte and temperature have been studied.The floatation coefficient and film coefficient of slag-matte system has been calculated and the mechanism of the transition of iron and oxygen from slag to matte has also been discussed.

Key words: interfacial tension, matte, slag, sessile drop method
