A critical review on destruction of thiocyanate in mining ...

Gold mills, which use cyanide for gold and silver extraction, often have a mixture of cyanide and thiocyanate in their effluents (Mudder et al., 2001, Akcil, 2003, Mudder and Botz, 2004). The cyanide reacts with both sulfide minerals and partially oxidized sulfur intermediates to produce thiocyanate ( Mudder et al., 2001 ).
