An ultra fast decopperization method from the anode slime has been developed based on the ultrasound-assisted leaching. The effects of parameters such as ultrasound power, leaching time, sulfuric acid concentration and liquid/solid ratio were investigated. Under optimum conditions, the concentration of Cu in residue was only 2.64%. The removal efficiency increases considerably and the decopperization time was significantly shortened comparing with conventional method (>10%, 24h). Se and Te have not been detected in lixivium, indicating the selective leaching of Cu. In addition, the mineralogical characteristics of the untreated anode slime and the residues after ultrasound-assisted decopperization are investigated. The results revealed that the increasing of decopperization efficiency was attributed to the change of the phase composition and the morphology and size of samples during ultrasound-assisted decopperization.
基于超声辅助浸出，开发了一种从阳极泥中快速脱铜的方法。研究了超声功率、浸出时间、硫酸浓度和液固比等参数的影响。在最佳条件下，残渣中铜的浓度仅为2.64%。与传统方法（>10%，24小时）相比，脱除效率显著提高，脱铜时间明显缩短。浸出液中未检测到硒和碲，表明铜的选择性浸出。此外，还研究了未处理阳极泥和超声辅助脱铜后残渣的矿物学特征。结果表明，超声辅助脱铜过程中脱铜效率的提高归因于样品相组成、形态和尺寸的变化。
