Regeneration of cyanide by oxidation of thiocyanate |
摘要 |
Provided is a method for regenerating cyanide from thiocyanate. The method comprises contacting the thiocyanate with an oxidizing gas containing ozone, generally a mixture of oxygen and ozone. The pH of the contacting medium is generally less than 7.0 to assure that HCN is the predominant species relative to CN-. The method has important applications to processes involving cyanidation procedures, such as gold leaching, plating and coal conversion.
