A Cornell University-led research team has created a new process to extract 99.9% of the gold from electronic waste to help turn carbon dioxide into useful organic materials. Discarded electronics are ...

Chinese researchers have discovered a fast, low-cost and environmentally cleaner method for extracting gold ...

Researchers have developed a new type of material that's 10 times more efficient at extracting gold from e-waste than previous adsorbents. Developed by chemists and materials scientists at the ...

A new method for recovering high-purity gold from discarded electronics is paying back US$50 for every dollar spent, according to researchers – who found the key gold-filtering substance in ...

ETH Zurich researchers have developed a sustainable method to recover gold from electronic waste. The method uses a sponge made from denatured whey proteins that selectively adsorb gold ions. The ...

Tackling the issues: Electronic waste is a growing problem. Each year, consumers produce millions of tons of used and broken electronics. Only a portion of the metals they contain are recycled because ...
