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

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

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 ...

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 ...

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.

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 ...

Gold mining significantly limits the regrowth of Amazon forests, greatly reducing their ability to accumulate carbon, according to a new study. The researchers warn that the impacts of mining on ...
