An attempt has been made in this study to optimize the process variables for the dephosphorization of iron ore using nitric acid. Standard central composite design with 23 full factorial was used to develop the model. The model was optimized using Matlab. The surface responses of the plots show that concentration interacted effectively with leaching time and particle size. The result shows that 99.74% degree of dephosphorization was obtained at optimum values of 120 minutes, 2.0 Moles and 10 microns
