Several deposits of iron ores are located in Bahariya Oasis, Egypt, in El Harra, El Heiz, Ghorabi, El Gedida, and Nasser areas. Nakhla and Shehata (1967) classified these iron ores into four types; (i) pisolitic ores, (ii) hard goethitic ores, (iii) soft ores with relatively high Mn contents, and (iv) ochreous ore.
