Iron Ores (Hematite and Magnetite) - GeeksforGeeks

09.11.2021  Magnetite is primarily used to extract iron in the form of pig iron or sponge iron. This produced iron is then used to make steel. Magnetite is also used as a catalyst. It is the catalyst used in the production of ammonia on an industrial scale. Hematite. Hematite is an iron ore that contains iron in the form of Fe 2 O 3. It is a significant source of iron extraction.

Which is better hematite or magnetite? – IronSet

05.10.2021  Which is better hematite or magnetite? 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.

Why we use hematite over magnetite as iron ore? - Quora

Answer (1 of 5): The structure of hematite is hexagonal and that of magnetite is BCT or inverse spinel. During reduction, the phase change in hematite takes place at a temperature of 500 deg C. This change brings with it an increase in the volume thereby increasing the porosity and increased indi...
