A Re-Introduction Midrex Technologies, Inc. - The Technology Leader in Direct Reduction Providing technology solutions to steelmakers around the world through practical innovations and continuous technology improvement Solutions engineered for specific steelmaker needs with flexibility to achieve more The leading DRI process technology provider in the world. More than 60 plants operating and even more currently under construction- including LGOK 3 & voestalpine Texas. 2 © 2013 Midrex Technologies, Inc. All rights reserved Description of the MIDREX® NG Process Simple, energy efficient closed loop gas system. Iron ore reduction to metallic (elemental) Fe occurs in MIDREX® Shaft Furnace Reducing gases generated in MIDREX® Reformer Simple design, minimized moving parts and unit operations, and no steam system results in very high availability © 2013 Midrex Technologies, Inc. All rights reserved. MIDREX® Process Simplicity Low pressure - less complex operation MIDREX® Reformer- Unique to MIDREX® Process Eliminates need for CO2 Removal System, Process Gas Heater, steam generation, etc. Fast start-up Reliability Proven long term availability demonstrated by the annual production of MIDREX® Plants worldwide –Actual Data NOT extrapolated data Built on State-of-the-Art technology - provides Reliable Operation, Increased performance while minimizing capital & operational costs Ongoing technology development allows older plants to expand capacity and remain competitive. Flexibility Widest range of oxide pellets and lump Production of CDRI/HDRI without interruption of process or product output 3 hot transport solutions for variety of site layouts all of which minimize fines generation © 2013 Midrex Technologies, Inc. All rights reserved. 4 MIDREX® Process An elegant and simple process that is proven to consistently produce highly metalized quality product Process gas experience allows for use of: Natural Gas, syngas from coal, pet coke, refinery bottoms, coke of gas (COG) and off gases from technologies such as COREX® and FINEX®. MIDREX® is the only DRI process that provides the ability to simultaneously produce any combination of product types Hotter Higher Quality HDRI with less fines due to mechanical conveying solution. Less fines Produced is crucial to CDRI & HBI yield More flexibility than any other process Technology available 5 © 2013 Midrex Technologies, Inc. All rights reserved. MIDREX® Shaft Furnace Capable of producing high quality Iron Oxide cold DRI (CDRI), hot DRI (HDRI), and hot briquetted iron (HBI) The MIDREX® Furnace can discharge hotter with less oxide coating producing higher temperature HDRI and export quality HBI Upper Seal Leg Low pressure inherently safer - operation allows gravity feed into and out of Shaft Furnace without requiring lockhoppers Packed bed reactor design results in Top Gas Outlet Reducing Gas Inlet high efficiency and productivity. Higher and more consistently metallized DRI produced due to uniform solids flow and gas flow inside Shaft Furnace. DRI © 2013 Midrex Technologies, Inc. All rights reserved. MIDREX® Reformer Proven Reliable Operation & Dependable Performance Very high reforming rate of CH4, CO2, and H2O into CO and H2. The MIDREX® process can handle any Natural Gas source regardless of sulfur or heavy hydrocarbon content Reaction CH4 + CO2 2CO + 2H2 CH4 + H2 O CO + 3H2 © 2013 Midrex Technologies, Inc.

Heat Endothermic Endothermic 7 Description CO2 reforming H2O reforming MIDREX® Reformer the best use of NG for DRI Production Not a typical steam reformer Flue Gas Collection Header MIDREX® Reformer- Reducing Gas Collection Headers Reforms natural gas and CO2 Eliminates need for CO2 Removal System, Process Gas Heater, steam generation, etc. Tubular type reformer, specifically designed to operate at low pressure Reformer Box Feed Gas / Air / Top Gas Fuel Headers © 2013 Midrex Technologies, Inc. All rights reserved. MIDREX® Environmental MIDREX® Plants are designed to minimize water, noise and air pollution. MIDREX® Plants meet applicable US standards and more importantly, Midrex will provide DR Plants designed to meet any local emissions or environmental standards regardless of location. Environment – setting the standard. The voestalpine Texas HBI plant will be the most environmentally conscious HBI plant in the world; including control for dust emissions and air emissions. Full range of Technologies/Innovative Equipment to handle Dust, reduce emission and improve water quality and maximize water usage/ recycle. Ammonia removal systems Baghouse Charge hopper dust collection De-Sulfurization systems Innovative burner systems to reduce NOx emissions/lower CO emmisions Sea Water Heat Exchangers to minimize water consumption © 2013 Midrex Technologies, Inc. All rights reserved. 9 MIDREX® CO2 Capture When there is a market to sell CO2 – very site specific for large quantities of CO2 Addition of CO2 capture will give clients up to 20% additional production Midrex has experience with VPSA, PSA and Ammine- based CO2 removal systems System can be taken offline without stopping production © 2013 Midrex Technologies, Inc. All rights reserved. 10 voestalpine Texas HBI Plant Project to use MIDREX® Technology for 2.0 MTPY HBI facility Annual capacity of two million tons of hot briquetted iron (HBI) The largest single HBI producing Plant in the world Most environmentally conscious HBI Plant to date; incorporates the latest air & dust emission technologies The consortium of Siemens and Midrex will provide engineering, supply of mechanical and electrical equipment as well as site services for the MIDREX® Plant. Designed with considerations for future CO2 capture “With Siemens and Midrex, we will have highly competent partners with a tried and tested technology at our side. By choosing a U.S. partner company, we are also making a significant contribution to the desired local value added,” - Wolfgang Eder, CEO and Chairman of the Management Board of voestalpine AG. © 2013 Midrex Technologies, Inc.

Mining Ore preparation Ironmaking (DRIorBF) Steelmaking (BOF or EAF) Casting Rolling Finishing A system with a bottleneck at the Ironmaking stage. All ensuing operations are restricted by the shortage of capacity at Ironmaking and you, the owner, are left paying for all fixed and related costs of the down unit, loss of profits AND possibly a down stream customer! Mining Ore preparation Ironmaking (DRIorBF) Steelmaking (BOF or EAF) Casting Rolling Finishing = Missed Expectations, Non-Productive Assets , Labor and Other Fixed Costs, + Lost Profits © 2013 Midrex Technologies, Inc.
