摘要：The effects of ultrasonic power, liquid-solid ratio and time on the vanadium leaching rate, surface tension, and contact angle were studied in this experiment. The optimum process conditions were determined: 10g for the sample; 1000w for ultrasonic power; 4:1 (mL/g) for liquid-solid ratio; 90 min for leaching time. The leaching rate of vanadium can reach 92.22%. The leaching rate of vanadium can be much improved with same time, when ultrasonic was used.
