The following is an introduction to these four types of iron ore, magnetite, hematite, limonite and siderite. Iron ore property. Iron is widely distributed in nature (the crust), but since iron is easily combined with other elements to form various iron minerals (compounds), there is little natural pure iron in the earth’s crust.

Minerals with Iron – Which Minerals Have the Most
The minerals with the highest iron content will be magnetite, hematite, goethite, and limonite. These minerals range in about 60% to 70%+ in iron content. Magnetite is the most widespread mineral on earth with roughly the highest iron content. This table shows the approximate percentage of iron in the mineral.

Hematite Iron Siderite - leslodges-marseille
Hematite is dense and hard, it is the most important ore of iron because of its high iron content and its abundance.The mineral occurs in various habits: steel-gray crystals and coarse-grained varieties with a brilliant metallic luster are known as specular hematite; thin, scaly forms make up micaceous hematite; and crystals in petal-like arrangements are called iron roses.

Siderite - Mineral Properties, Photos and Occurence
Siderite is both an iron ore and gangue mineral. Its principal economic value lies in its high iron content and the absence of process contaminants such as sulfur or phosphorous. It is part of a large group of isomorphous minerals, the calcite group carbonates, which share similar physical properties, and rhombohedral crystal form.
