Iron-Oxide Concretions and Nodules - Meteorite Information

Meteorite or Meteorwrong. Iron-Oxide Concretions and Nodules. Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch people's attention and they are denser than most other rocks.

The importance of mineralogy and petrology on the ...

The efficiency of any iron ore value-adding operation is closely associated with detailed knowledge of the mineralogy, especially in the processing of lower grade and complex ores. There are a number of physico-chemical properties of iron oxide mineral phases (eg goethite, hematite and magnetite) that can be prudently exploited to enhance their processing efficiency.

Limonite has been used as a low-quality iron ore for thousands of years. Commercial mining of limonite as a source of iron is no longer done in areas where reasonable deposits of hematite and magnetite are present or readily imported. Limonite deposits are usually too small and too impure for use in …

Hematite: A primary ore of iron and a pigment mineral

Uses of Hematite (Iron Ore) Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.

Iron Ores - Technische Fakultät

Goethite is no longer important in iron making. Its importance in older times is unclear to me because it was not distinguished from siderite or bog ore. Goethite forms by "weathering" of more primary iron ores like magnetite or pyrite, involving a change from Fe(II) compounds to the more stable Fe(III) form.
