从含钒铬物料中分离提取钒铬的研究进展

Research Progress on Separation and Extraction of Vanadium and Chromium From Vanadium&Chromium-bearing Materials

含钒铬物料硅铝含量高、成分复杂,钒、铬分离是钒铬物料资源化的关键。综述了从含钒铬物料中分离提取钒、铬的工艺,分析了各工艺的优缺点,认为碱浸法具有更好的应用前景。

The vanadium chromium-bearing materials have higher content of silicon and aluminum. The key problem of the materials reutilization was separation vanadium from chromium. The recovery processes for separation and extraction of vanadium and chromium from vanadium＆chromium-bearing materials were summarized, the merits and demerits of these processes were analyzed. It was considered that the alkali leaching process would have good application prospect.
