K4Fe (CN)6+K2CO3 = 5KCN+KCNO+Fe+CO2. The cyanide so formed is always contaminated with cyanates and carbonates, and generally with small amounts of other salts (sulphides, chlorides, thiocyanates, etc.). The procedure frequently adopted at present is to fuse with metallic sodium: K4FeCy6 + 2Na = 4KCy + 2NaCy + Fe;

In cyanide extraction process of silver from argentite ore ...

The extraction of silver involves in cyanide process are:(i) Ag2S + 2CN- + O2 → 2[Ag(CN)2]- + SO2(ii) [Ag(CN)2]- + Zn → [Zn(CN)4]2- + AgThus, in equation (i) O2 act as oxidising agent (Oxidise sulphide to SO2) and in (ii) Zn act as reducing agent (reduce Ag+ to Ag).
