| titleOfInvention | Method for producing vanadium product and basic chromium sulfate by using vanadium-chromium solution |
| abstract | The invention relates to a method for producing vanadium products and basic chromium sulfate by using a vanadium-chromium solution, which comprises the steps of hydrolyzing and precipitating vanadium, carrying out calcification reaction, enriching chromium, preparing basic chromium sulfate and the like to obtain high-purity vanadium products and basic chromium sulfate products, wherein the purity of the obtained vanadium products can reach more than 99.5 percent, and Cr in the basic chromium sulfate 2 O 3 The content can reach 24-26%, the content of impurity Fe is less than 0.1%, the recovery rate of vanadium and chromium can reach more than 99.5%, and the purpose of efficiently extracting and separating vanadium and chromium is realized. The production process is clean, the brine and the NaOH mother liquor generated in the preparation process can be returned to a system for use, and no ammonia nitrogen wastewater is generated in the whole process flow. The invention has the advantages of feasible technology, simple equipment, low production cost, easy realization of automation, and good economic benefit and application prospect. |
