Difference Between Magnetite and Hematite Definition ...

2018-1-31  Magnetite and hematite are two forms of iron ores from which iron can be extracted. Magnetite contains iron in the form of Fe 3 O 4. Hematite contains iron in the form of Fe 2 O 3. The main difference between magnetite and hematite is that magnetite is ferromagnetic whereas hematite is paramagnetic. Key Areas Covered. 1. What is Magnetite

how to tell between hematite and magnetite? - White Iron

What is similar about magnetite and hematite? Almost all iron oxides are iron oxides, including magnetite (Fe3O4) and hematite (Fe2O3). While both minerals contain iron (Fe), their oxidation states are different. In hematite, Fe is primarily present in the 3+ form. Iron is not only found in magnetite
