Abstract: Invention relates to a process of producing solid sodium cyanide. The process according to the invention is characterized in that an aqueous sodium cyanide solution (1) of 30 to 45% by mass, containing up to 5% by mass solids, is granulated in two process steps in counterflow with heated air, wherein in the first process step a fluidized bed is produced in a fluidized bed granulator (4) by means of hot air (5) from the second process step, in so doing the air being cooled down to a temperature of 60.degree. to 90.degree. C. a sodium cyanide granulate of 2 to 6 mm being set in a classifying discharge duct (16) and the same being dried to a residual moisture of 1.5 to 4% by mass, wherein in the second process step in a further fluidized bed of a drier (14) the granulate produced is dried through an air current (25) with initial temperatures of 150.degree. to 230.degree. C. to a residual moisture settable at liberty of less than 1.5% by mass and is removed by way of a cellular wheel (20 ).
