Zusammenfassung:	The processing for reconditioning of waste cement kiln dust to reuse the valuable metal salts thereof as a combination soil conditioner, liming agent and potassium-enriched fertilizing material, wherein water is admixed with the waste dust in a carbon dioxide-containing atmosphere to primarily reduce the alkalinity of the dust and to secondarily granulate the mixture.
