| Abstract: |
| Ferric vanadate was prepared from coal vanadium ore leaching solution. The effects of type and dosage of oxidant, reaction time, pH value, and temperature on precipitation were investigated. V2O5 precipitation rate is 93.73% under the optimum conditions including dosage of sodium chlorate of 1.4 times of theoretical value, reaction time of 5 h, pH value of 2.5, and reaction temperature of 90~95 ℃. |
