Cyanide Leaching Recreational Gold ProspectingAbout the Cyanide Code International Cyanide Management

Cyanide is destroyed by sodium thiosulfate or sodium nitrite An average fatal dose of HCN is about 50 60 milligrams Cyanide dissolves both gold and silver from alkaline solution Cyanide is a very “clean” extraction system as it does not extract many of the base metals such as ironThe International Cyanide Management Code For the Manufacture Transport and Use of Cyanide In the Production of Gold Cyanide Code was developed by a multi stakeholder Steering Committee under the guidance of the United Nations Environmental Program UNEP and the then International Council on Metals and the Environment ICME
