| Abstract: |
| The effects of temperature, concentration of sodium hydroxide and sodium carbonate, and dosage of sodium hypochlorite on vanadium leaching rate and viscosity of lixivium were investigated. The results show that increasing temperature can improve vanadium leaching rate and increase viscosity of lixivium. Increasing concentration of NaOH, Na2CO3 and NaClO improves vanadium leaching rate and decreases viscosity of lixivium. Vanadium leaching rate and viscosity of lixivium is ~61% and 5.4 mPa?s respectively under the optimum conditions including temperature of 90 ℃, dosage of sodium hypochlorite of 0.249%, concentration of sodium hydroxide of 150 g/L, and concentration of sodium carbonate of 90 g/L. |
