Removal behavior of Pb, Ni from liquid copper by Cu2O-Fe2O3 based slag with one or two additive oxides among CaO, B2O3, SiO2, P2O5 and TiO2 was investigated in the temperature range from 1,200 to 1,300 °C. The results obtained are as follows,<BR>1) The Pb removal was largely increased by the addition of acidic oxide, but the Ni removal was at most 50 % for all slag compositions investigated.<BR>2) The addition of P2O5 and TiO2 was obtained nearly same good results as the addition of B2O3. Thus, P2O5 and TiO2 was found to be practically used as a substitute for B2O3.<BR>3) The Ni removal was enhanced by increasing temperature, which could be explained to the decrease of activity coefficient of NiO. However, The Pb removal was retarded by increasing temperature.<BR>4) The kinetic behavior of Pb and Ni removal by oxidizing slags could be well simulated by the reaction model based on the two film theory.
