Iron Ore Reduction - an overview - ScienceDirect
Currently the dominating process for the iron-ore reduction is the blast furnace (BF) technology. These furnaces consist of a moving bed reactor with a counter-current flow of the solid reactants against a reducing gas. Not only are the energy costs relatively high for these blast furnaces the pollution problems can also be quite severe.
Pellets for Direct Reduction
Table of ContentsProperties and Quality DemandsMetallurgical Test MethodsLKAB Pellets for Direct Reduction The iron ores mined by LKAB in the north of Sweden have excellent beneficiation properties.

Direct reduced iron - Wikipedia
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example bein…

4.5.2.3.5 Physical Observation of the Iron ore Fines During Reduction. Iron ore fine reduction depending on its density will likely reduce either in a topochemical reduction [136] or a complete uniform internal reduction mode [137]. Most dense iron ores typically exhibit a topochemical reduction mechanism and is shown in the following.
