Therefore, using microwave or ultrasonic treatment could obviously reduce the leaching time and improve leaching efficiency.
利用微波或超声波辅助处理，可以大幅度缩短浸提时间，提高浸提效率。

Experiment manifests that the leaching rates of zinc dross are elaborately enhanced and the leaching time of zinc oxide finished ore is shortened by means of ultrasonic strengthening.
试验表明利用超声波强化浸出锌浮渣可大大提高了锌浮渣的浸出率，缩短了浸出时间。
