Abstract As the volume of e-waste continues to rise, it is crucial sustainably manage printed circuit boards (PCBs) and their valuable metal components. PCBs are ubiquitous in modern society, powering a variety electronic devices. The resource crisis imperative for low-carbon circular economy have accelerated development recycling technology. High-value discarded represent vital component e-waste. However, deemed hazardous ecosystem due presence heavy metals brominated organic polymers. Thus, from not only strategic necessity fostering green ecological civilisation but also guarantee ensuring safe supply mineral resources. This comprehensive review gives profound details PCBs, performance advances latest chemical recovery methods. Reviewing processes, we explored application diverse leaching agents, including ionic liquids (ILs), deep eutectic solvents (DESs), acids amino acids. These were assessed terms efficiencies, most them demonstrated excellent performance. role optimising parameters such as concentration, oxidants, pH, particle size, solid-to-liquid ratios (S/L), temperature, contact time underscored, offering insights into achieving sustainable PCB practices. Most these recent methods successfully extracted base (Cu, Fe, Zn, Sn, etc.), well precious (Au Ag), efficiencies exceeding 90.0%. Interestingly, effectiveness can compete with that traditional hydrometallurgical
