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

Researchers in China have introduced a room-temperature process that extracts over 98% of gold from discarded electronics, including old phones, in less than 20 minutes, at a cost of about US$1,455 ...

Beneath a mountain of discarded electronics, a team of Australian scientists has unearthed a new way to extract gold — without the environmental toll. In a breakthrough published in Nature ...

Scientists have figured out a way to recycle important metals trapped inside electrical waste. Using textiles, researchers from the Korea Institute of Science and Technology (KIST) have improved the ...

An interdisciplinary team of experts in green chemistry, engineering and physics at Flinders University in Australia has developed a safer and more sustainable approach to extract and recover gold ...

Refractory gold ores present significant challenges to conventional extraction methods. In these ores, gold is tightly encapsulated within sulphide minerals or locked by carbonaceous matter, thereby ...

ZURICH, Switzerland, March 6, 2024 (ENS) – Transforming base materials into gold was one of the unachieved aims of ancient alchemists. But now Professor Raffaele Mezzenga from the Department of Health ...

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 ...

Gold recovery from carbonaceous ores represents a significant challenge in mineral processing due to the inherent presence of organic carbonaceous matter that can adsorb gold cyanide complexes, a ...

A team led by Cornell researchers has devised an innovative method to recover gold from electronic waste and repurpose it as a catalyst for converting carbon dioxide (CO 2) into organic compounds.

Gold recovery curves were similar with average gold recoveries of 65.6% after 30 days, 85.6% after 60 days, and 92.2% at the completion of the tests. The tests were completed on oxide and transition ...
