A process for producing shaped articles of inorganic cyanides, in particular alkali metal cyanides and alkaline earth metal cyanides, comprising shaping of particle – form inorganic cyanide, obtained by a crystallization process, by means of a device for shaping the particle – form cyanide by press moulding, characterized in that a cyanide crystallisate with a total water content of from 2 to 15 wt.%, separated off from a mother liquor during the crystallization process by means of a solid/liquid separating device, is fed to a shaping device without the addition of a shaping a auxiliary and press moulded under pressure into shaped articles with a water content in the range of from 0.1 to 12wt. %, wherein the water content of the shaped articles is always lower than that of the crystallisate used in the production thereof.
