“…Furthermore, it is also estimated that the recovery of gold from WEEE would decrease the environmental and mining footprint along with savings of 17,000 tonne per tonne in carbon dioxide emissions. providing both good Cu recovery and separation from the WPCB resin, but its potential for leaching other metals has not been explored [95]. Simple acid leaching in air has also been studied and dilute HCl (1.0 M) shown to lixiviate gold and other metals to a high degree from…”

Noble metals are valued, critical elements whose chemical activation or recycling is challenging, and traditionally requires high temperatures, strong acids or bases, or aggressive complexation agents. By using elementary palladium and gold, demonstrated here is the use of mechanochemistry for noble‐metal activation and recycling by mild, clean, solvent‐free, and room‐temperature chemistry. The process leads to direct, efficient, one‐pot conversion of the metals, including spent catalysts, into either simple water‐soluble salts or metal–organic catalysts.
