A process for the production of gold and ammonium cyanide comprising: a) providing a cation exchange resin in ammonium form, by passing an aqueous solution of an ammonium salt through and in contact with a cation exchange resin in the form of hydrogen, whereby exchange of the hydrogen ions of the resin by the ammonium ions of the solution occurs, and b) then passing an aqueous solution of a gold and alkali metal cyanide through and in contact with the resin of cationic exchange in ammonium form, whereby the ammonium ions are exchanged from the resin by the alkali metal ions in the solution and an effluent containing gold and ammonium cyanide is produced.
