gold cyanide production plant cianor

Gold

Gold is commonly processed with cyanide, which is highly toxic. Most of the cyanide is destroyed in the production process, so it is not present in the final product, but it can be a hazard to workers in a gold processing plant. Since gold conducts electricity, gold jewelry should never be worn when working with electricity.
