EN The chapter presents some aspects of metal leaching from e-waste. It focuses on new leaching systems containing ionic liquids (ILs) for recovery of copper (mainly) from waste printed circuit boards (PCBs). It is reported that the most efficient are acidic ILs with bisulfate anion, and they perform even better than sulfuric acid. However, the results of the leaching show that IL agent should be supported by the presence of some oxidants (e.g. H2O2) to increase the process efficiency. Nonetheless, the use of ILs seems to be a perspective option to make the leaching more intensive and effective, a lot of basic research is necessary to investigate the mechanism of the Cu leaching, and to find optimum process conditions.
