Researchers developed a couple of processes for extracting gold from e-waste and using it in drug manufacturing.
involves selective steps for the sustainable leaching and recovery of base metals like nickel, then copper, silver and, finally, gold, using green and safe reagents.The gold produced from this process, however, is part of a molecular compound and cannot be reused for electronics without investing a lot more energy to obtain the yellow metal.
They found that the gold compound performed as well, or better, than the currently used catalysts, and is also reusable, further improving its sustainability.recover gold from electronic waste
