Extracting gold from ore is a poisonous business. The most common method is cyanide leaching, where cyanide salts in solution are used to suck the gold out from its ore. You get gold, but you also get ...

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 ...

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 ...

There's treasure in trash — literally. Discarded computers, circuit boards, and other electronic waste contain valuable metals like gold. Now, breakthrough research could make extracting gold easier ...

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 ...

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 ...

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 ...

The extraction methods currently in use consume a lot of energy and are detrimental to the environment. The method of roasting is particularly dangerous for its practitioners and the environment ...
