摘要: 将黑色岩系(石煤)钒矿粉碎后与复合添加剂混合,经转窑氧化焙烧、水淬浸取与湿法球磨分级、双重搅拌动态浸取与交换、饱和树脂清洗与解吸、解吸液除杂与沉钒、粗钒脱水与脱氨等工序,生产出高品质五氧化二钒。通过对上述各工序影响钒浸出率的因素进行综合试验与工业实践,总结出从黑色岩系(石煤)钒矿中提取五氧化二钒的新工艺。该工艺实现了石煤钒矿中钒的焙烧转化浸出率在80%以上,矿粉中钒的综合回收率大于70%,产品质量优于YB/T 5304—2006《五氧化二钒》98级的要求。

Abstract: High-quality vanadium pentoxide was prepared by the following process:black shales (stone coal) vanadium ore crushing,compound additives mixing,oxidating and roasting in a rotary kiln,water quench leaching and wet milling grading,dynamic leaching and exchange under double stirring,saturated resin cleaning and desorption,desorption solution purifing and vanadium precipitation,and crude vanadium dehydration and deamination.Through comprehensive testing and industrial practice to the influencing factors of each procedure on leaching rate of vanadium,a new technology of extracting vanadium pentoxide from black shale (stone coal) vanadium ore was summed up.Technology realized more than 80% vanadium leaching rate from roasting stone coal vanadium ore,the comprehensive recovery of vanadium was over 70%,and product quality was better than YB/T 5304—2006 Vanadium Pentoxide Standard.

Key words: black shales (stone coal), vanadium pentoxide, technical research, industrial practice
