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 ...

The Precious Metals E-Waste Recovery market offers promising opportunities driven by rising e-waste volumes, eco-friendly ...

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 ...

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 ...

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 ...

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 ...

While you won't get rich off your old electronics, cleaner methods for extracting materials like gold is a win for the environment. In 2025, it’s not uncommon for a typical household to have a drawer ...

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 ...

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.
