Chinese scientists have developed a rapid e-waste mining method that extracts gold in under 20 minutes at around one-third of ...

EXCLUDING mechanical, smelting, and amalgamation processes, the methods of extracting gold from its ores may conveniently be grouped together under the heading of wet or chemical methods. In these, ...

Scientists at Australia’s national science agency, CSIRO, have developed a new process designed to improve gold recovery and recycle toxic cyanide used in mining. The method, called ‘Sustainable Gold ...

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 ...

The wildcat gold mining boom that swept across the Amazon beginning in the 1970s left behind an environmental catastrophe of ...

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 ...

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 ...
