This study investigated the geochemical and mineralogical characteristics combined with heavy elements concentrations of Cement kiln dust (CKD) in Ain Sukhna industrial area, North‐western part of the Gulf of Suez, Egypt and the influence of flash floods in its stability. Flooding severity is moderate with several water erosional processes. The CKD characterized by very poorly sorted/very fine‐sands to silt. CaO and SiO 2 are major components with enrichment of chloride/sulfate ions. High enrichment of Sr, Zn, Pb, Cd, Sb, and Se are related to variations in shale/limestone feeds during cement formation. The threshold effect level exceeds the standard value for Cd, Pb, and Zn at S3 that indicates adverse biological effects. Sylvite, calcite, and halite minerals were dominated. Three main principal components recognized the shale, calcium/magnesium carbonate dissolution, and the scavenging effect of sulfate for heavy elements. Monitoring the CKD leachability and proper management plans are prerequisite for environmental protection in the future.
