on the use of cynade in gold extraction

Hydrogen Peroxide and Caro's Acid Powerful Oxidants . 2020 8 17 A brief review of the use of peroxygens to destroy free CN, WAD weakly acid dissociable CN and tightly complexed cyanides will be followed by a case history on the use of Caro's acid peroxymonosulfuric acid to treat cyanide in a tailings slurry at a large North American Gold mine.

Cyanide Use in Gold Mining

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and;
