volatilization roasting
1.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(ηGa) ,how-er,the effect decrease with over addition.
