Magnetite: The mineral Magnetite information and pictures

Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.

What is Magnetite? (with pictures) Info Bloom

Niki Foster. Magnetite is a type of iron oxide with natural magnetic properties. In fact, it is the most magnetic naturally occurring mineral on Earth and was once used in compasses. Its chemical name is ferrous-ferric oxide, and its chemical formula is Fe 3 O 4.. Magnetite was used by ancient civilizations to magnetize compass needles.

MAGNETITE (Iron Oxide) Amethyst Galleries Mineral Gallery

Magnetite is an oxide of iron (as is hematite).It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite.

Magnetite Wikipedia

Magnetite is a 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

Magnetite Meanings and Crystal Properties The Crystal

Magnetite is an iron oxide mineral that crystallizes in the form of masses, octahedral, and dodecahedral crystals. Its color is usually silver or black, but can also be seen as grey and brown. Magnetite is the most magnetic mineral in the entire crystal kingdom (hence its name). It is believed that this mineral provided ancient civilizations

Magnetite: Mineral information, data and localities.

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).

Gemstone Information Magnetite Meaning and Properties

Magnetite is a rock mineral and, along with hematite, is mined as one of the main iron ores. Scientists have discovered evidence that magnetite exists in the human brain and have theorized its presence can affect long-term memory. Magnetite power was used by the Germans in the 1930s to develop magnetic acetate tape for audio recording.

Magnetite. Magnetite is strongly magnetic. It was used by the ancient Chinese to make the first magnetic compasses. The chemical formula is Fe 3 O 4, commonly called ferrous-ferric oxide, and is valuable as an iron ore. Magnetite reacts with oxygen to produce hematite, another iron ore. In crystalline form magnetite is usually octahedral.

The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identification becomes a rather routine exercise. The mineral magnetite is named after this characteristic.. Magnetism occurs (most often) when there is an imbalance in the structural arrangement of the iron ions.
