Different Types of Iron Ore - Mineral Processing & Metallurgy

Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content. Goethite and turgite come between hematite and limonite in composition, and are found with both, but are comparatively rare.

Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch people's attention and they are denser than most other rocks. Hematite concretions form by precipitation of iron oxide from iron rich solutions.
