gold recovery with cyanide

Leaching and recovery of gold from ore in cyanide-free ...

2020-11-1  1. Introduction. Currently, cyanide is the predominant lixiviant used to extract gold due to its strong complexation with gold and the technical simplicity of the leaching process (Avraamides, 1982, Habashi, 1987, Marsden and House, 2006).However, the use of cyanide can bring challenges in terms of environmental, health and safety aspects (Aylmore, 2005, Laitos, 2012).

2021-5-23  As far as the gold on pottery goes you would have to process a heck of a lot since it's only a few millionths of an inch thick. You can kill the cyanide with calcium hypochlorite for disposal. I once got about 3 oz of gold off mil spec connector pins but I had to process about 27 pounds of them. Good luck and be very careful with the cyanide.
