The new gold-extraction technique, which they describe in a new paper published today in Nature Sustainability, could also make small-scale gold mining less poisonous for people – and the planet.

An interdisciplinary team of experts in green chemistry, engineering and physics at Flinders University in Adelaide, Australia, says it has developed a safer and more sustainable approach to extract ...

In 2022, humans produced an estimated 62 million tonnes of electronic waste – enough to fill more than 1.5 million garbage trucks. This was up 82 per cent from 2010 and is expected to rise to 82 ...

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 ...

Thiosulfate leaching is emerging as a promising alternative to traditional cyanidation methods in gold extraction. This process utilises thiosulfate as a lixiviant, offering enhanced environmental ...

A groundbreaking new technology for gold extraction from cyanide processes is revolutionizing the mining industry by significantly boosting precious metal recovery rates through the recycling of this ...
