A method of reclaiming and inhibiting activation of DRI including forming a moving stream or pile containing DRI pellets and DRI fines and applying to said DRI material a coating material optionally having a melting point between 70 and 200° F. and comprising at least one antioxidant and at least one a carboxylic material with at least one selected from the group consisting of coatable fatty acid and an esterified derivative thereof, forming a coating on the DRI pellets and DRI fines to cause the fines to adhere together and to the pellets to form a plurality of DRI agglomerates. The coating material may be selected from the group consisting of palm oil, coconut oil, combinations thereof, and ester derivatives thereof. The antioxidant in the coating material is selected from the group consisting of at least one of butylated hydroxytoluene, carotenoid, phytosterol, squalene, vitamin E, tocopherols, tocotrienols, and mixtures thereof.
