Micro–sintering equipment was applied to simulate sintering process of iron ore. FeO content of sintersamples under different fuel structures was measured, and then the effect of fuel structure on fluidity of liquid phase and strength of bonding phase were analyzed in this paper. The proper fuel structure was finally discussed under low FeO sintering condition.

to identify a highly stable, pyritestructured iron oxide (FeO 2) at 76 gigapascals and 1,800 kelvin that holds an excessive amount of oxygen. We show that the mineral goethite, FeOOH, which exists ubiquitously as 'rust' and is concentrated in bog iron ore, decomposes under the deep lowermantle conditions to form FeO 2 and release H 2. The ...

So the g of iron that formed came from the iron oxide. So let's calculate how much iron oxide was used. 1st. We'll convert to malls of iron. one wall of iron is grants. And then we'll use the mole ratio. There is one mall of f. e. three oh four in three moles of F. E. And then we'll multiply by the molar mass to 31 to get the mess of iron oxide.
