A method of producing nickel rich iron alloy by increasing the nickel concentration of the alloy in a converter having molecular-oxygen containing gas blowing comprising adding nickel-bearing iron ore and molecular oxygen containing gas to the converter at a rate which maintains the temperature in the converter between 1,550 DEG and 1,650 DEG C., carrying out the blowing and addition of ore in a plurality of steps, and removing, after each step, the slag produced at each step of blowing with addition of ore so that the weight of the slag removed after each step is smaller than four times the weight of the alloy produced after the end of the corresponding step of blowing and addition of ore.
