Lateritic Deposits Laterite ores formed through the intense weathering of primary rocks in tropical and subtropical climates. However, commercial magnetite ores usually contain iron in the 30% to 40% range due to impurities.
Geological Basis of Iron Ore Types Classification
The key characteristic of magnetite is its oxidation state; when processed, it releases oxygen and transforms into hematite, a process that generates heat. Classification by Geological Formation Beyond mineralogy, iron ore types are categorized by the geological processes that created them.
The two dominant categories are Banded Iron Formations and residual laterites, each representing distinct periods in Earth’s geological history. The two main subtypes are hardcap and limonite laterites, which require different processing techniques, often involving high-temperature reduction rather than traditional magnetic separation.

This analysis provides a detailed overview of the mineral classifications, chemical profiles, and market implications of the world’s iron resources. Ores with higher iron content, or "head grade," are more valuable because they yield more metal per ton of rock processed.
