how do we calculate iron ore
How is iron ore priced? - Financial Times
The Steel Index receives prices of physical iron ore trades from companies buying or selling iron ore, takes out the high and low outliers, standardises the different traded products The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast 23.3: Metallurgy of Iron and Steel - Chemistry LibreTextsIron ores consist of oxygen and iron atoms bonded together into molecules. To convert it to metallic iron, it must be smelted or sent through a direct reduction process to remove the oxygen. Oxygen-iron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen. Carbon is used because the strength of a carbon-oxygen bond is greater than that of the iron-oxygen bond at high temperatures. Thus, the iron orIron ore - Wikipedia
Iron processing Definition, History, Steps, Uses, Facts
iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which Iron Ore Statistics and Information U.S. Geological Survey2024年4月26日 Iron ore processing is a complex and vital process that transforms raw iron ore into usable steel.

Iron processing - Ores, Smelting, Refining Britannica
Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, The production of iron from its ore involves a redox reaction carried out in a blast furnace. The furnace is filled at the top with the iron ore oxide most commonly hematite ( Fe2O3 Iron Production - Chemistry LibreTexts
