Hematite Magnetite Difference

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

Which is better hematite or magnetite? – IronSet

The mineral magnetite actually has higher iron content than the mineral hematite. However, while hematite ore generally contains large concentrations of hematite, magnetite ore generally holds low concentrations of magnetite. Magnetite ore’s magnetic properties are helpful during this process.
