摘要: 介绍了钒渣提钒工艺过程钒铬的分离回收现状, 分析了现行钒铬分离回收工艺的优缺点。结合钒铬分离回收研究取得的最新进展, 指出钒渣提钒工艺改进的方向是在获得钒铬合格产品的同时, 实现主要化工原料及水在工艺过程的循环利用, 进一步节能减排。Abstract: The present status and prospects of vanadium and chromium separation in vanadium extraction from vanadium-chromium slag were introduced in this paper,and the advantages and drawbacks of the existing vanadium-chromium separation and recovery processes were analyzed. Combined with the latest developments in the areas of vanadium-chromium separation and recovery,it is proposed that besides obtaining qualified vanadium and chromium products,the improvement of vanadium extraction from vanadiumchromium slag mainly lies in the energy conservation and emission reduction,realizing the cycle and utilization of water and major raw materials in the processes.
