Characterization of Chemical Composition and

The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (south-western Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties.

Iron Ore an overview ScienceDirect Topics

The chemical composition of many fine iron ore products continues to decline with time as higher-grade reserves are replaced with lower-grade reserves for both direct-ship and beneficiated products. It is expected that this trend of declining iron ore product grades is most likely to continue well into the future.

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. Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at a high
