采用超声波对某磷矿进行预处理选矿，研究了超声波作用时间与作用功率对颗粒表面电位的影响；超声作用对矿物颗粒粒径的影响；擦洗脱泥和浮选2种选矿方式对超声波强化效果的对比。结果表明，在不改变浮选药剂制度或擦洗条件时，使用超声波前处理能显著提高磷矿富集。
採用超聲波對某燐礦進行預處理選礦，研究瞭超聲波作用時間與作用功率對顆粒錶麵電位的影響；超聲作用對礦物顆粒粒徑的影響；抆洗脫泥和浮選2種選礦方式對超聲波彊化效果的對比。結果錶明，在不改變浮選藥劑製度或抆洗條件時，使用超聲波前處理能顯著提高燐礦富集。

Ultrasonic was used for pretreatment of the mineral separation process. The effects of ultrasonic time and ultrasonic power on the potential of the particle surface were studied. Then, the effect of ultrasonic on the particle size was studied. Scrubbing and lfotation were chosen for the contrast study of the strengthening effect of ultrasonic. The efifciency of phosphorus enrichment would be improved signiifcantly when the reagent system of lfotation and the conditions of scrubbing were not changed.
