Ultrasonically-enhanced leaching: correlating acoustic spectra and solid particle properties in NMC cathode extraction.

ABSTRACT: Dissolutions are entailed in a wide variety of industrial processes, and acoustic cavitation is being researched as a powerful tool to intensify these processes. In particular, when applied to the leaching of battery cathode material in hydrometallurgical recycling, it paves the way to the utilization of organic acids in place of mineral acids, lowering the hazardousness and cost of recycling. In this framework, mapping the cavitation activity and understanding the relation between acoustic cavitation and the action of the acid is fundamental for the design and control of the intensified process. This work used the leaching of NMC (lithium nickel manganese cobalt oxide) cathode particles as a model system. Leaching reduces the average particles size from 10 μm to 1.5 μm, reflecting the 85
