Effect of Ultrasound on the Oxidative Copper Leaching

2020-6-10  Chalcopyrite represents nearly 70% of known copper resources [3,4]. Pyrometallurgical smelting has been the industry-standard method to extract copper from high-grade chalcopyrite, but the use is restricted due to environmental problems (i.e., SO 2 emissions) and the depletion of rich ore deposits increasing the processing costs [5,6].
