    01-07-2010 · In the leaching of gold using cyanide, copper presents difficulties due to the lack of selectivity of cyanide for gold over copper (Rees and van Deventer, 1999). Cyanide also forms complexes with a number of metal irons: Fe(CN) 6 4− , Ni(CN) 4 2− , Zn(CN) 4 2− and Ag(CN) 2 − which decrease the free cyanide concentration in slurry and retard gold leaching( Rees and
