Zusammenfassung:	A method is provided for the recovery and recycle of nitrate and nitrite salts present in environmentally hazardous chloride containing quench bath solids, comprising the steps of leaching the solids with hot water to provide an aqueous leachate that depletes the hot water soluble content of the solids, clearing the resulting aqueous leachate of solids, and recycling it while hot into a fused quench bath.
