Abstract

Abstract

This paper deals with the chloridizing volatilization of Ga and conversion of vanadium into water-soluable vanadium by mixed roasting with addition of activated carbon and liquid pulp containing carbon to V-slag,NaCl and Na₂CO₃ at a low temperature of 400℃ and a medium temperature of 800℃.The results indicates that addition of activated carbon can remarkably increase the chloridizing volatilization of Ga (η_Ga),how-er,the effect decrease with over addition.Addition of pulp at 400℃ remarkably increase η_Ga,which is higher than that at 800℃ with addition of either activated carbon or pulp to roasting.Simultaneous addition of activated carbon and pulp doesn't help to increase the η_Ga.For chloridizing volatilization of Ga,it is most favourable to add only activated carbon to roasting at 400℃.The highest η_Ga obtained from this experiment is 35.1%.The conversion rate of vanadium to water soluable vanadium (ηv.t) is low at 400℃ without addition of Na₂CO₃ in the roasting burden.Both a higher η_Ga and a higher ηv.t may be expected with the ratio of pulp addition being 0.05 mL/g and W_Na₂CO₃/W_NaCl=2.
