Many electronic items you use daily, including your laptops, chargers, and smartphones, contain a tiny amount of gold. This is because gold is an excellent conductor of electricity and doesn’t rust or ...

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 ...

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 ...

Adsorption—not alchemy—can transform waste into recycled gold. A protein sponge made from food waste recovers gold from e-waste, creating high-purity nuggets (Adv. Mater. 2024, DOI: ...

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 ...

At Flinders University, scientists have cracked a cleaner and greener way to extract gold—not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool ...

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 ...

Justin M. Chalker is an inventor on patents associated with the gold leaching and recovery technology. Both patents are wholly owned by Flinders University. This research was supported financially by ...
