Abstract: A study on the dephosphorization of Agbaja Iron Ore using hydrometallurgical process has been carried out. The central composite design of 23 response was formulated and used to develop a model equation. The optimized result of the equation using Matlab shows that 97.97% degree of dephosphorization was obtained at 117 minutes leaching time, 0.2M leachant concentration and particle size of 30 microns. Iron loss during the hydrometallurgical leaching was less than 5%. It can be inferred that chemical leaching using HCl is attainable under the prevailing conditions of the experiment.
