Iron Ore Distribution across the World

Banded Iron Formations (BIFs) are layers of iron-rich minerals interleaved with sedimentary rocks. Formed approximately 1.8 to 2.5 billion years ago during the Precambrian age, BIFs are the primary source of iron ore globally. They predominantly contain hematite and magnetite. Hematite, characterized by its red-brown color, is prized for its high iron content and minimal impurities. Magnetite, on the other hand, is magnetic and contains iron up to 70%.

Magmatic magnetite ore deposits, usually associated with igneous intrusions, are formed when magma cools down and crystallizes. The magnetite crystallises earlier than other minerals, which leads to iron-rich magma forming substantial magnetite deposits. This type of deposit is less common than BIF but can contain high-grade iron ore.

Hematite ore deposits, typically found in places with a history of volcanic activity, are formed when volcanic materials weather and decompose over time. Hematite here is often found in the form of kidney ore, specularite, and micaceous hematite, each with varying iron content and physical properties.

Besides these, limonite and siderite are other important types of iron ore. Limonite, a mixture of hydrated iron oxides, is lower in iron content than hematite or magnetite but is often mined for applications where its particular characteristics are needed. Siderite, composed of iron carbonate, has a lower iron content and is often used in industries where its specific chemical properties are required.

Understanding these types and formations is crucial for mining strategies and for predicting the location of new deposits, influencing global iron ore exploration and economic planning.
