Hematite Physical Optical Properties, Occurrence, Uses

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.

Iron ore Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO

or unavailable. It also depends largely on the chemical composition and reactivity of both the host rock and the hydrothermal solution. In iron ore, hematite/martite is often replaced by goethite from its core region ( Fig. 3a ). Euhedral crystal of hematite is also found to be replaced by goethite from its peripheral margin ( Fig. 3b ).
