| titleOfInvention | A method of extracting vanadium chromium from vanadium chromic acid mixed salt solution |
| abstract | The method that the present invention relates to a kind of to extract vanadium chromium from vanadium chromic acid mixed salt solution, the characteristics of this method is, first using the vanadium in crystalline deposit method or hydrolysis methods or calcium salt precipitation method separation and recovery vanadium chromic acid mixed salt solution, again with the chromium in the mantoquita precipitation method or barium salt precipitation method separation and concentration solution, gained chromium precipitating enriched substance made the transition again chromium pregnant solution, the pregnant solution of chromium be further processed chromic acid and chromate product, effectively prevent the generation of vanadium chromium separation and recovery process vanadium chromium reducing slag and ammonia nitrogen waste water in solution.The present invention has the good separating effect of vanadium and chromium, and process flow is short, and metal recovery rate is high, and easy to operate, production cost is low, and advantages of environment protection is suitable for industrialized production and application. |
