Difference Between Magnetite and Hematite

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
