Classification by Geological Formation Beyond mineralogy, iron ore types are categorized by the geological processes that created them. This analysis provides a detailed overview of the mineral classifications, chemical profiles, and market implications of the world’s iron resources.
Magnetite vs Hematite: A Detailed Comparison of Iron Ore Types
Ores with higher iron content, or "head grade," are more valuable because they yield more metal per ton of rock processed. Hematite (Fe2O3) Hematite is often regarded as the most important iron ore types due to its high iron content, which typically ranges between 56% and 70%.
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. The two dominant categories are Banded Iron Formations and residual laterites, each representing distinct periods in Earth’s geological history.

Known for its striking red color, which results from iron oxidation, hematite is a dense and relatively stable mineral. However, commercial magnetite ores usually contain iron in the 30% to 40% range due to impurities.
