  Extraction of Iron | Metallurgy | Blast Furnace and Reactions

  The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state. A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into ...

  Influence of Iron Ore Characteristics on FeO Formation During …

  201151 · The results indicate that LOI (loss on ignition) in iron ores have a positive influence on FeO formation by promoting the sintering process of Fe 2 O 3 decomposing and reducing. Silica contents in iron ores play a determining role in final content of FeO in sinter. The melting characteristics of iron ores significantly affect FeO formation ...

  22.5: Reduction of Metals - Chemistry LibreTexts

  Since iron is the most important metal in our industrial civilization, its reduction from iron ore in a blast furnace (Figure 22.5.1 22.5. 1 ) deserves a detailed description. The oxides present in most iron ores are Fe 2 O 3 and Fe 3 O 4. These oxides are reduced stepwise: first to FeO and then to Fe.

  Surface Morphology and Structural Evolution of Magnetite-Based Iron Ore ...

  2022323 · The use of magnetite-based iron ore fines by means of fluidized bed technology has become a promising route to produce direct reduced iron. The significant influence of a prior oxidation treatment, which occurs in the preheating stage, on the subsequent fluidization and reduction behavior was observed in our previous study. As a …

  Direct Reduced Iron and its Production Processes – IspatGuru

  2013316 · Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes. The reducing …
