| Abstract: |
| This paper researching the leaching performance of vanadium mineral resource-stone coal which is a unique resource in China. By the study of curing vitriol dosage, curing temperature, curing time, leaching time, leaching temperature etc, presenting the new technology of vitriol curing-leaching that leach vanadium, leaching rate reaching 94%, it has an important significance to actual production process of extracting vanadium from stone coal. |
