抄録

As a fundamental study of a new zinc smelting process using liquid copper for a smelting medium recover zinc in a liquid Cu-Zn base alloy, distribution ratios of zinc, L^S_Z/^C_N, between liquid Cu-Zn-Fe (ironsaturation) alloys and CaO-Si0₂-FeO_X slags were determined at 1, 473 and 1, 523 K, under varying content in the alloy from about 0.5 to about 30 mass% and varying Q (Q=%CaO/(%CaO+%SiO₂)) of the slag from 0 to 1.<BR>L^S_Z/^C_N for the alloy with alow zinc content about 0.5% is alrnost constant against% FeO_x in the slag and decreases with increasing Q. The activity coefficient of ZnO in the slag, (γz_no>), which was calculated from the measured L^S_Z/^C_N, increases with increasing Q and is about 3 at Q=0.42.<BR>L^S_Z/^C_N for the alloy with a high zinc content more than 1% increases monotonously with the zinc content.The calculated (γz_no) is almost constant against the zinc content. This suggests that ZnO in the CaOSiO₂-FeO_x-ZnO slag approximately obeys a Henry's law up to the relatively high concentration of ZnO.(γZnO) inCreases with increasing Q and is about 5 atQ=1.<BR>Based on the obtained L^S_Z/^C_N, the fractional distribution of zinc between the alloy, slag and gas phases was calculated for the newly proposed process to recover zinc by means of the smelting medium of liquid copper.
