From jewelry to advanced electronics, gold's value is undeniable. Its unique properties and widespread use make it an ...

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 ...

Discarded electronics can be a gold mine – literally. Researchers have developed an efficient new way to use graphene to recover gold from electronic waste, without needing any other chemicals or ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...

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 ...

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: ...

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 ...

Researchers have used gold extracted from electronic waste as catalysts for reactions that could be applied to making medicines. Re-using gold from electronic waste prevents it from being lost to ...

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 ...

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 ...
