The process is almost same as pig iron production processes. The only difference is that the ore contains more nickel. The blast furnace products contain 2-10% of nickel. A new approach is usage of electric arc furnaces toThe MIDREX Process - The world’s most reliable and,,3 The MIDREX® Process MIDREX® DIRECT REDUCTION FLEXIBILITY Million Tons/Year 0 0.5 1.0 1.5 2.0 2.5 3.0 Series 400 Series 600 MEGAMOD SUPER MEGAMOD Prototype Plant Size ®The MIDREX Process can: • derive reducing gas from the energy source most readily available and competitively priced • efficiently reduce local iron oxide pellets and ores ofProduction - voestalpine Stahl Donawitz GmbH,New technologies deal with the direct reduction of ores to a directly reduced material (DRI or HBI). In this process iron ore pellets are reduced in a shaft furnace using natural gas. The advantage of this technology is the saving of approx. 40% CO

IMMTFeasibility study on different iron ore samples for possibility of beneficiation. (M/s. ESSAR Steel, Visakhapatnam.).Direct reduced iron - Wikipedia,Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).The Cyber-Physical System for Increasing the Efficiency of,,The Cyber-Physical System for Increasing the Efficiency of the Iron Ore Desliming Process .
