摘    要:超声波技术的广泛应用基于超声波所具有的两种特性,一是超声波作为一种信息载体,二是超声波作为一种能量形式。本文所总结的超声波在矿物浮选方面的应用,正是基于超声波作为一种能量形式,通过它(或者由它所产生的超声空化)与传声介质相互作用所产生的效应,从而对矿物浮选产生影响。本文从超声波应用于矿物浮选的原理出发,综述超声波对矿物、浮选药剂和矿浆产生的作用及应用现状,总结应用于浮选的超声波设备,最后提出超声波应用于浮选的发展展望。结果表明:超声波效应会对浮选产生不同作用,可通过设置不同的超声波参数和不同的处理方式调控浮选行为,改善浮选指标,从而达到所需的目的。

Abstract: The wide application of ultrasonic technology is based on two characteristics of ultrasonic, one is ultrasonic as an information carrier, the other is ultrasonic as a form of energy. The application of ultrasonic in mineral flotation summarized in this paper is based on the fact that ultrasonic is a kind of energy form, it (or the ultrasonic cavitation produced by it) interacts with the acoustic medium to produce an effect on mineral flotation. This work is based on the principle of ultrasonic applied to mineral flotation, and summarizes the effect and application status of ultrasonic on minerals, flotation reagents and pulp, also summarizes the ultrasonic equipment used in flotation, and finally puts forward the development prospect of ultrasonic application in flotation. The results show that the ultrasonic effect has different effects on flotation. Different ultrasonic parameters and different treatment methods can be set to regulate the flotation behavior and improve the flotation index, so as to achieve the purpose we need.
