POTASSIUM CYANIDE | 151508
Contact with acid releases highly flammable hydrogen cyanide gas. Moisture may cause POTASSIUM CYANIDE to volatilize as hydrogen cyanide. When heated to decomposition, POTASSIUM CYANIDE emits very toxic fumes of cyanide and nitrogen oxides. Reacts with acids to produce hydrogen cyanide gas.

Permanganate Oxidation with NaCN: Potassium permanganate can also be used to oxidize cyanide, although it is not widely practiced. The method is advantageous because hydroxide ion is a product of the reaction, keeping the medium alkaline throughout the reaction. and the permanganate oxidizes the cyanide only to cyanate.
Gold cyanidation
Remaining free cyanide degrades in the pond, while cyanate ions hydrolyse to ammonium. Studies show that residual cyanide trapped in the goldmine tailings causes persistent release of toxic metals ( mercury ) into .
Capsule Report: Managing Cyanide in Metal Finishing
Noncyanide sil ver and goldplating processes have also been developed but are not generally well accepted. Effective substitutes for cyanidebased brass, bronze, silver and gold processes, as well as less common plating processes, are still in de velopment. Table 6 provides and overview of cyanide and noncyanide plating processes.

The process of extracting gold from ore with cyanide is called cyanidation. The reaction, known as Elsner's Equation, is: 4 Au + 8 CN+ O 2 + 2 H 2 O = 4 Au(CN) 2+ 4 OHAlthough the affinity of cyanide for gold is such that it is extracted preferentially, cyanide will also form complexes with other metals from the ore, including copper, iron and zinc.
