Classification by Geological Formation Beyond mineralogy, iron ore types are categorized by the geological processes that created them. Magnetite (Fe3O4) Magnetite is distinguished by its strong magnetic properties and contains a higher percentage of iron than hematite, theoretically up to 72.

This inherent magnetic nature makes it exceptionally easy to separate from waste rock using magnetic separation techniques, giving it a significant advantage in the initial concentration phase. These deposits are generally lower in iron concentration, ranging from 25% to 60%, and contain higher levels of impurities like aluminum and silica.
The classification moves beyond simple percentages to identify the specific crystalline structures that make up the ore body. BIFs are typically found in very large, bulk-mining operations due to their immense scale.

Understanding the specific iron ore types is essential for investors, metallurgists, and industrial planners who require precise data to optimize extraction and processing. These sedimentary rocks consist of alternating layers of iron-rich minerals and silica or chert.
