Abstract The interfacial tension between FeO-CaO-SiO-MgO system slag andCu-Fe-S system matte was determinated by the X-ray radiograph sessile drop method.The effects of FeO/SiO ratio in the slag, contents of CaO, FeO, ZnO and CaF_2 inthe slag on interfacial tension and the relation of interfacial tension with the gradeof matte and temperature have been studied. The floatation coefficient and film coef-ficient of slag-matte system has been calculated and the mechanism of the transitionof iron and oxygen from slag to matte has also been discussed.

Key words: Interfacial tension matte slag sessile drop method
