1. A method for producing granulated metallic units (GMUs), the method comprising:
receiving a first supply of molten iron;
producing GMUs by granulating the molten iron poured onto a target material of a reactor;
removing residual fines of the GMUs via a classifier, based on a threshold particle size between 1-10 mm; and
mixing the residual fines with a second supply of molten iron, different than the first supply of molten iron, to produce additional GMUs.
