Abstract
Fe, mn, and w were recovered economically and efficiently from slag by the electrolysis of a silicate/chloride 2-phase melt with graphite electrodes, the anode in contact with both phases, and the cathode with the chloride phase. Thus, nacl with napo3 and b2o3 to enhance diffusion of metal ions between layers, were added to slag containing sio2 42, na2o 18, feo 11, wo3 0.8, and mno 14 pct. After 4 electrolysis cycles at 1,000 deg. C metal recovery was fe 57.2, Mn 36.5, and w 62.5 pct.
