Impurities of NaOCN and K4Fe(CN)6 in sodium cyanide.

[Stowmaster]

Please tell me, whether you can use for gold cyanide leaching mixture containing NaCN+KCN and impurities NaOCN+KOCN (max 25%) and K4Fe(CN)6 (max 10%)? Can these impurities to spoil the process?

They sure can spoil the process--you'd be well-served not to have the iron in there (which makes it harder to recover).
