Cyanide-free recovery of gold from electronics, mining and other secondary sources

The aim of the project is to contribute to a more sustainable and efficient gold extraction process from secondary sources such as electronics and mining waste. The process is a combination of the non-toxic thiosulfate method for gold leaching and CFA's proprietary metal separation technology in aqueous solutions. The technology will be adapted to gold-containing material in lab experiments and then developed to pilot scale. The Energy Agency deems that the project has the potential to contribute to a more sustainable resource use by increasing the re-circulation of gold from waste to market.
