This study explores the potential of ultrasound as a process intensification technique for the extraction of lead from landfilled metallurgical residues. The research focuses on a comparison between silent leaching using acidic sodium chloride and sonicated leaching. In silent conditions, lead leaching reaches 45% after a three-stage process, while ultrasound dramatically accelerates the process, achieving the same yield in just 30 minutes—a factor of eight times faster than silent leaching. Overall, the yield improves by 19-26% with ultrasound application. The improvements in yields are discussed with respect to reaction kinetics, and the physical effects of ultrasound on particle size are investigated using laser diffraction analysis. Furthermore, the study shows that using ultrasound in a multi-stage process leads to achieving yields at the end of the 3rd stage in silent conditions within the 2nd stage, coupled with 20% greater selectivity. This highlights the significant efficiency benefits of incorporating ultrasound into the leaching process.
