Abstract
Methods for producing cyanide salts using a metathesis process using ion exchange to facilitate a double-decomposition reaction where components of a cyanide-containing compound are exchanged to produce a cyanide salt product are provided. In one embodiment of the invention, HCN may be converted to an alkali salt using a base. The alkali cyanide salt undergoes ion-exchange to yield the desired cyanide salt product. In another embodiment of the invention, hydrogen cyanide is directly converted to cyanide salts in an ion exchange bed without first being converted to a basic salt.
