Magnetite & Lodestone | Mineral Photos, Uses,

Magnetite is one of the most common iron minerals and an important ore of iron. The magnetite crystals in this photo are about eight to twelve millimeters in maximum dimension. Magnetite as "Lodestone" Normal magnetite is attracted to a magnet, but some specimens are automagnetized and have the ability to attract small pieces of iron, small pieces of magnetite, and other magnetic objects

Iron Ore | Geoscience Australia

Mineral magnetite contains 72.4% iron, which is higher than hematite but the presence of impurities results in lower ore grade, making it more costly to produce the concentrates used in steel smelters. Magnetite mining is an emerging industry in Australia with large deposits being developed in the Pilbara and mid-West regions of Western Australia, and in South Australia.

Mineralogy: magnetite & hematite – minerals

28.02.2011· The first mineral on our tour was quartz. Most weeks, we'll only cover one mineral, but there was a very strong push to include magnetite & hematite when I polled the blogosphere, so I chose to add both. Both magnetite (Fe3O4) & hematite (Fe2O3) are iron oxides. However, the oxidation state of iron

Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces
