A New Technology of Extracting Vanadium from High Calcium Low-grade Stone-coal

文章对高钙低品位石煤提钒工艺进行了研究,提出了选矿冶炼联合提钒新工艺,并获得了理想的浸出效果。该工艺与传统工艺相比,可有效降低冶炼成本,提高钒的回收率,开辟了低品位石煤钒矿提取五氧化二钒新途径,提高了低品位钒矿的资源综合利用率。

This paper has studied the process of extracting vanadium from high calcium low-grade stone coal. It has proposed a new technology of extracting vanadium by dressing-smelting, and obtained satisfactory leaching re- suits. Compared with the traditional process, this process can effectively reduce smelting costs and increase the re- covery of vanadium. It has developed a new ways of extracting vanadium from stone-coal, and increased the lowgrade mineral resources comprehensive utilization of vanadium.
