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, ...

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

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 ...

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 ...

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 ...

Swirling together immiscible liquids in a separatory funnel or seeing crystals materialize in a beaker might be some of the more entertaining activities in undergraduate chemistry labs. But these ...
