摘　　要：研究了石煤钒矿在富氧条件下的焙烧试验,考察了氧浓度、焙烧温度、焙烧时间等因素对钒浸出率的影响。结果表明,在氧浓度65%、焙烧温度860℃、焙烧时间210min的条件下,平均钒浸出率可达到84.5%,且生产五氧化二钒全流程总钒回收率为80.28%。Oxygen-enriched air roasting of vanadium-containing carbonaceous shale was studied, aimed at the influences of oxygen concentration, roasting temperature and roasting time on the vanadium leaching rate. The results show that under the conditions of oxygen concentration of 65%, roasting temperature of 860℃ ,roasting time of 210 min,the average vanadium leaching rate can reach 84.5%, and the total vana- dium recovery is 80.28% in the whole process to produce vanadium pentoxide.
