| 摘 要： | 文章首次提出原矿磨矿因素是含钒硅质岩焙烧-酸浸提钒工艺影响钒浸出率的主要因素之一，采用单因素条件试验方法对此进行了实验研究论证。结果表明，采用不同磨矿方式，钒浸出率有较大差别；不论采用何种磨矿方式，细磨后的矿粉筛分，-0．074mm矿粉具有较好的钒浸出率指标。

| Abstract: | This paper first presents that the influence of grinding mode on ore is one of the main factors to recovering V2O5 by roasting-acid leaching from the siliceous navajoite,based on one-factor experimental design.The results show that different grinding mode on ore leads to different leaching rate of V2O5,and no matter what way grinding,if the mineral powder is sieved,-0.074mm slag has good leaching rate of V2O5. |
