Review A systematic review of gold extraction: Fundamentals
However, the shortcomings of cyanidation are increasingly prominent. Recently, few breakthroughs in cyanidation have been carried out, while non-cyanide leaching is the current hotspot in gold hydrometallurgy (Aylmore, 2016). Nevertheless, cyanidation will still dominate for a long time, and it is still worth further investigation. (1)

Gold Cyanidation Leaching Process
The cyanidation leaching time depends on the material properties, cyanidation method, and conditions. Generally, agitation cyanidation leaching lasts more than 24 hours, sometimes extending to 40 hours, while gold telluride cyanidation requires 72 hours. Percolation cyanide leaching, on the other hand, takes more than 5 days.
