利用超声波预处理、浮选试验、电感耦合等离子体发射光谱和X射线光电子能谱分析等手段，考察了不同超声波预处理方法对方铅矿浮选行为的影响。对单一方铅矿样品进行处理后，提高了方铅矿的浮选回收率，这主要归功于声空化有效地去除了方铅矿表面的氧化组分和污染物。但是，采用方铅矿和黄铁矿混合样品处理后，方铅矿的浮选回收率降低。电感耦合等离子体光电子能谱(ICP-OES)和X射线光电子能谱(XPS)分析结果表明，超声处理有利于PbS转化为PbSO4和PbSO4。此外，在超声波预处理过程中，方铅矿与不同粒度的黄铁矿混合时，对方铅矿的浮选回收率也有不同程度的影响。原因是这两种矿物的表面积比的变化影响了方铅矿和黄铁矿之间的电化学反应速度。
Utilizing the ultrasonic pretreatment, flotation tests, ICP-OES, and XPS analysis, the effect of the different ultrasonic pretreatment methods on the flotation behavior of galena were investigated. The flotation recovery of galena was improved for pretreated single galena sample, which is mainly attributed to the efficient removal of the oxidized components and contaminants on the surface of galena by the acoustic cavitation. However, the flotation recovery of galena was decreased when pretreated mixture sample of galena and pyrite was used. Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) and X-ray photoelectron spectroscopy (XPS) results reveal that ultrasonic pretreatment facilitates the conversion of PbS to Pb(OH)2 and PbSO4. Besides, the flotation recovery of galena was affected to varying degrees when the galena was mixed with the pyrite of the different particle sizes in the ultrasonic pretreatment process. The reason is that the change in the surface area ratio of these two minerals affects the electrochemical reaction rate between galena and pyrite.
