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

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 ...

Researchers in China have introduced a room-temperature process that extracts over 98% of gold from discarded electronics, ...

In 2022, humans produced an estimated 62 million tonnes of electronic waste – enough to fill more than 1.5 million garbage trucks. This was up 82 per cent from 2010 and is expected to rise to 82 ...

Transforming base materials into gold was one of the elusive goals of the alchemists of yore. Now Professor Raffaele Mezzenga from the Department of Health Sciences and Technology at ETH Zurich has ...

In a recent paper published in the Journal of Chemical Engineering Journal, researchers from the Korea Institute of Science and Technology announced that they have created a technology that uses ...

Inside all TVs, computers, mobile phones, gaming consoles, and other electronic devices lies a circuit board of some sort, and inside that circuit board lies gold. Though it only exists in tiny ...

Thiosulfate leaching is emerging as a promising alternative to traditional cyanidation methods in gold extraction. This process utilises thiosulfate as a lixiviant, offering enhanced environmental ...
