Metal extraction from e waste. 61 J/mol. Additionally, novel technologies like bio-metallurgy cryo-milling, siderophores and supercritical extraction technology also resulted in enhanced recovery efficiencies for base and precious metals, along with metal recovery techniques using recyclable lixiviates. In this study, we critically have reviewed the existing extraction processes and compared among different processes such as physical, biological, supercritical fluid technologies, pyro and hydrometallurgical, and hybrid methods used for metals extraction from e-waste. These results demonstrate that discarded LCD panels can serve as a reliable secondary source of rare and critical metals, and the developed process provides a practical and scalable solution for e-waste recycling. Waste printed circuit boards (WPCBs), as the main component of the waste, are significant source of base and precious metals, especially copper and gold. which it is only possible to safely smelt the non-ferrous metal This process not only provides an avenue to reclaim valuable metals but also supports sustainability and environmental conservation by reducing electronic waste. Herein, the valuable metal recovery driven by the development of a circular economy has increasingly become a focal point in research. Feb 16, 2026 · Recycling printed circuit boards (PCBs) is crucial for reducing pollution, recovering valuable metals, and conserving resources. This study presents a green method for metal extraction from mobile phone PCBs using citric acid (C6H8O7). Pyrometallurgical and hydrometallurgical processes have been developed to extract metals from Feb 13, 2025 · As electronic waste (e-waste) piles up globally, researchers at the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment and the Stanley and Karen Pigman College of Engineering are spearheading innovative methods to recover valuable metals from discarded devices and industrial waste. ljdyhuslrzgfnchtsbvawyjrcsevyllqbzrodtbybkfryikxhss
