Magnetite ore is found mostly in Tamil Nadu, and karnataka whereas hematite is found in odisha, jharkhand, madhya pradesh. 3. Magnetite is the best quality iron ore whereas hematite is inferior to magnetite.Hematite (Fe2O3) and magnetite (Fe3O4) are two ores used,,15-01-2013· The two ores of iron are hematite and magnetite with the chemical formula Fe2O3 and Fe3O4 respectively. To determine which of the compounds has a higher percentage of iron per kilogram first the,Hematite - Wikipedia,Hematite (/ ˈ h iː m ə ˌ t aɪ t, ˈ h ɛ m ə-/), also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3).Oxidation states of the metal in the minerals haematite,,So there are two oxidation states of iron in magnetite ore. The first oxidation state of iron: 2 x + 3 ( − 2) = 0. ⇒ x = + 3. The second oxidation state of iron is: x − 2 = 0. ⇒ x = + 2. So, the oxidation states of iron in magnetite are +2 and +3. Therefore, the correct answer is an option (D)- (III) in haematite, and (II), (III) in,Production of pelletizing concentrates from,,Zandrivierspoort magnetite/haematite ore by magnetic separation by P.
