Following two systems of slag were prepared, (1) In the slag of SiO2-Al2O3-FeO system, SiO2 was replaced by Al2O3 (2) In the slag of SiO2-Na2O-FeO system SiO2 was replaced by Na2O. These slags were fused with the commercial matte under desired condition.
Then, the suspended matte and the dissolved matte in those slags was separated respectively by brommethanol leaching and analysed for copper photoelectric-colorimetrically, and also, viscosity of those slags
were measured by rotating boll method and obtained following results:
1) The higher content ofAl2O3 incresed the viscosity of slags slightly and the amount of suspended matte in slags, but decreased the dissolved matte in slags. The total Cu losses in slags were eliminated by Al2O3.
2) Na20 in slags decreased theviscosity, both suspended and dissolved matte in slags.
3) The higher temperature and the increased the dissolved matte and decreased the suspended matte, so tho total amount of copper losses in slags were a little.
