Crude Zinc Oxide Dust RecoverySlag/Dross Recovery
Crude zinc oxide () is one of the important resource of zinc metal extraction. The main source of crude zinc oxide includes: a. flue dust collected from EAF (electrical arc furnace); b. fume dust collected from zinc leaching residue treatment by waelz kiln; c. zinc fume dust collected from lead slag treatment by fuming furnace.
RECOVERY OF VANADIUM FROM VBEARING BOF .
Slag formers were chosen aiming for a liquid slag at a process temperature of 1650°C. The method is based on prereduction using carbon based reductants and finalreduction using ferrosilicon and/or aluminium powder. During reduction of BOFslag, chromium, iron, phosphorous, manganese and vanadium will be reduced into the metal phase.
