Module-E, one of the largest MIDREX direct reduction plant in the world with more than 2.5 MT iron oxide consumption. The oxides used in its Shaft Furnace (SF) is in pellet shape of size 6 to 18 mm diameters. However, during palletization process at suppliers’ locations, and transportation afterward, undersized pellets are generated. In the plant, undersized materials are screened off from feeding materials and sent to by-product hoppers prior the SF. Hence, having good screening system is crucial in minimizing oxides loses. In previous study, it was estimated that more than 50% of 3-6mm fines in by-product hoppers contain larger than 6 mm oxide pellets and 85% is +5mm oxide pellets. These good materials can be utilized in the SF. Recently, new oxide screens with new configuration were installed. The proper modification of the oxide screens at Module-E showed noticeable saving of more than 45,000 Tons/year as a prime iron oxide. Keywords: *Iron pellets; Process optimization; Oxide screens*
