2015-11-4  Abstract: The optimum gravity separation conditions for beneficiation of iron ores from Itakpe and Ajabanoko were studied using shaking table. Bulk representative samples were collected from the two locations and their chemical and mineralogical compositions were determined using X-ray fluorescent and microscope respectively. The mineralogical studies of the two deposits shows that hematite is the most dominant iron mineral in the Itakpe iron ore while magnetite is the most dominant iron mineral in the Ajabanoko iron ore. Results of the chemical composition analyses indicated that the grade of Itakpe iron ore is 36.18 % Fe while that of Ajabanoko is 34.14 % Fe. The results of determination of concentration criteria shows the two deposits can also be beneficiated
