《MetallurgicaandMaterialsTransactions》1997年28卷（B）第4期上，发表K.SarveswaraRao等人文章，介绍超声波对氨浸氧化铜矿石的影响。由于对铜需求量的增加，导致全球努力用各种湿法冶金方法去开发低品位的氧化铜矿石，因此需要开发一种从这些矿石中提取铜的工艺。当前，使
Metallurgica and Materials Transactions, 1997, Vol. 28 (B), No. 4, published by K. Sarveswara, Rao et al., Describes the effect of ultrasonic waves on ammonia-impregnated copper ores. As the demand for copper has increased, leading to global efforts to develop low grade copper oxide ores using various hydrometallurgical methods, there is a need to develop a process for extracting copper from these ores. Currently
