Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
Which is the richest iron ore?
Seven countries with the largest crude iron ore reserves in the world
- Australia – 48 billion tonnes.
- Brazil – 29 billion tonnes.
- Russia – 25 billion tonnes.
- China – 20 billion tonnes.
- Ukraine – 6.5 billion tonnes.
- Canada – 6 billion tonnes.

Which is the highest grade of iron ore?
The highest quality and most important iron ores for steelmaking are hematite (Fe2O3) and magnetite (Fe3O4). Hematite is the more sought-after ore and the preferred raw material in efficient steelmaking mills.
How much iron ore has been mined?
Iron mining in the United States produced 48 million metric tons of iron ore in 2019. Iron ore was the third-highest-value metal mined in the United States, after gold and copper. Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah.

Is siderite a carbonate ore?
Siderite is a mineral composed of iron(II) carbonate (FeCO3). It takes its name from the Greek word σίδηρος sideros, “iron”. It is also a common diagenetic mineral in shales and sandstones, where it sometimes forms concretions, which can encase three-dimensionally preserved fossils.
