摘　　要：本论文采用熔融-焙烧-水浸法工艺从山阳某含钒石煤中提取提钒。着重对焙烧和浸出条件进行了优化,包括过氧化钠用量、焙烧时间、焙烧温度、浸出方式及是否灰化处理等。结果表明:在试样与过氧化钠用量比为1∶3、焙烧温度为700℃、焙烧时间为7 min时钒的浸出效果较佳,其浸出液钒的浓度为1.38 mg/L。In this article,vanadium is extracted from a vanadium-bearing stone coal in Shanyang by the process of melt-roasting-water leaching.The experimental roasting and leaching conditions were optimized,including sodium peroxide dosage,roasting time,roasting temperature,leaching method and ash treatment.The results showed that the leaching rate of vanadium was maximum when the dosage of sample and sodium peroxide was 1∶3,roasting temperature was 700℃and roasting time was 7 min.The concentrations of vanadium in the leaching solution were found to be 1.38 mg/L in the leaching samples at the optimum working conditions.
