Magnetite Black Iron Oxide Fe304 Powder Info Amp Quote Magnetite is a natural iron oxide magnet hence the name giving it a very nice distinguishing characteristic Magnetite is the most magnetic of all the minerals on Earth Magnetite is a member of the spinel group which has the standard formula AB2O4 The A and B represent different metal ions that occupy specific sites in the crystal structure.
Dec 09 2012 Magnetite an iron ore with formula Fe3O4 can be reduced by treatment with hydrogen to yield iron metal and water vapor a Write the balanced equation Use the lowest possible coefficients 1Fe3O4s 4H2g 3Fes 4H2Og b This process requires 36 kcal for every 1 00 mol of Fe3O4 reduced How much energy in kilocalories is required to produce 63 g of iron kcal.
Magnetite Iron Ores most specific character is its magnetism It is the most magnetic mineral in the world Additionally in comparison with Hematite Iron Ore iron processing from Magnetite Iron Ore is much less harmful due to less carbon emissions producing The product from magnetite ore is also of higher quality than from hematite ore.
Prior oxidation of magnetite ore to Fe 2 O 3 leads to similar reduction behavior when compared with natural hematite however natural magnetite is hardly reducible due to low porosity and the formation of dense intermediate products during the reduction 8 Accompanying oxides in the iron ore such as alumina influence the reduction rate.
Dec 13 2002 Magnetite may be the most important ore of iron It is found at Kiruna Sweden and in other regions of ancient and metamorphic rocks It rarely forms beautiful shiny black octahedral crystals as well as rhombododecahedrons It is hard 5 5 65 and rather heavy d 5 18 gcc It dissolves in hydrochloric acid and of course is strongly.
