ABSTRACT:
The oxidation of metal-complexed cyanide under acid conditions using oxygen as the oxidizing agent can be performed effectively with certain metal chelates as catalysts. Especially effective chelates are metal phthalocyanines, particularly where the metal is vanadium or a member of the iron group metals. The oxidation can be effected homogeneously using water soluble metal chelates, or can be performed heterogeneously, especially in a continuous fashion using a packed bed reactor, by using suitable water-insoluble metal chelates, especially when supported on appropriate carriers.
