Of the various compounds of iron occurring in nature, but four may be considered as relatively common – pyrite, magnetite, hematite, and limonite. Pyrite consists of iron and sulphur; magnetite, hematite, and limonite are oxides of iron. The firstnamed mineral differs largely from the others in external appearance as well as in composition.

Jul 02, 2013 · Limonite – Wikipedia, the free encyclopedia. The streak of limonite on an unglazed porcelain plate is always brownish, a character which distinguishes it from hematite with a red streak, or from magnetite . »More detailed
The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite, limonite or siderite. Hematite is also known as "natural ore". The name refers to the early years of mining, when certain hematite ores contained 66% iron and could be fed directly into blast furnaces.
· Limonite and martite showed better reducibility than coarse and fine hematite. At all ore types the growth of dense magnetite rims was observed. The thickness of these layers was found to be linear proportional to reduction time.
Hematite is one of the most common minerals. The color of most red and brown rock, such as sandstone, is caused by small amounts of Hematite. It is also be responsible for the red color of many minerals. Noncrystalline forms of Hematite may be transformation s of the mineral Limonite that lost water, possibly due to heat. Chemical Formula. Fe2O3.
comprise brown hematite (limonite and possibly turgite), magnetite, mixtures of magnetite and hematite, and titaniferous magnetite (mix tures of magnetite with ilmenite or with rutile). Hematite alone also occurs, but the quantity is small, and it has never been mined. The brown hematite, magnetite, and titaniferous magnetite ores have

Limonite is a common iron ore, which forms the coloring matter in different types of soils. It is usually formed from the chemical weathering of iron rich minerals, such as biotite, amphibole, pyroxene, and olivine, the hydration/oxidation of iron rich sulfide minerals, or .
Limonite is a matrix base of many other minerals, and the term gossan is used as a reference to Limonite when it is used as a a matrix for another mineral or has formed an undesirable staining on top of it. Limonite is extremely common and forms the coloring matter in many soils.
· Magnetic separation of hematite and limonite fines as. Jun 01, 2002· The experimental results from this work have shown that an efficient magnetic separation of hematite and limonite (weakly magnetic minerals) in the fine size range can be achieved at a middleintensity if the mineral fines are selectively and strongly aggregated, leading to a great decrease at field intensity and gradient.
