Iron ore - WikipediaIron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite.hardness of sand and iron ore,Magnetite & Lodestone | Mineral Photos, Uses, PropertiesMagnetite is one of the most common iron minerals and an important ore of iron. .

Magnetite is a rock mineral and one of the main iron ores. With the chemical formula Fe3O4, it is one of the oxides of iron. Magnetite 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.

Properties. The most striking property of magnetite is very strong ferrimagnetism. It makes the mineral easily identifiable because it is strongly attracted to a hand magnet. . Hardness is about 6 on the Mohs scale. . In some places beach sand may be so concentrated in magnetite that it could be used used as an iron ore.
Jul 26, 2016 . More water softeners are used to remove iron from water supplies than any other devices or systems. Many of these installations are successful and consistently remove both hardness and iron. At other installations, intermittent leakage of iron through the softener occurs, but the total water.
Feb 28, 2017 . Hematite, the common iron ore, invariably has a red-brown streak. Some minerals are very soft; others very hard. The degree of hardness is an aid in identifying the minerals. Diamonds are harder than quartz and will therefore scratch quartz, quartz will scratch calcite, calcite will scratch gypsum, and so on.
