British and American researchers have recently discovered a simple and non-hazardous compound that is capable of selectively extracting gold from an assortment of metals that are typically found in electronic waste. The way to use this selective binding in a simple protocol for recovering gold efficiently is illustrated in the Angewandte Chemie journal.
Recycling gold from jewelry or electronic scraps—think computer chips and circuits lined with thin layers of gold—is not without issue either. Annually, Foley explained, the world produces more than 50 million tons of electronic waste per year; that amount is increasing rapidly due to non-stop innovation that shortens the life span of electronic devices.
The hydrometallurgical processes produce acidic leachates during the recovery of PMs from waste sources, while the selective recovery of Au, Pd, or Pt from such a matrix is challenging either due to the chemical similarities of elements or complexities in the sources and matrices.

E-waste is classified as hazardous material therefore should be managed properly. However, the presence of precious metals (PMs) in e-waste such as gold (Au), silver (Ag), platinum (Pt), Gallium (Ga), palladium (Pd), tantalum (Ta), tellurium (Te), germanium (Ge) and selenium (Se) makes it attractive for recycling.
