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 ...

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 ...

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.

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 ...
