VERVIEW OF CYANIDE TREATMENT METHODS

Cyanide treatment processes are classified as either a destruction-based process or a recovery-based process. In a destruction process, either chemical or biological reactions are utilized to convert cyanide into another less toxic compound. Recovery processes are a recycling approach in which cyanide is removed from the solution or slurry and then re-used in a metallurgical circuit.
