Magnetite occurs in many sedimentary rocks. It is generally found in beach sand and in banded iron formations. Magnetite is found in large quantities in North and South America, Europe, and New Zealand. Magnetite is eroded into rivers and carried to the beach, where it accumulates in sand. It is then concentrated via wave action and currents.

Magnetite is a mineral that is part of the spinel group. It is considered the most magnetic mineral that naturally occurs on Earth. It is black or brownish black in color and can often be found ...
Iron ore can be found all over the world, in the form of rocks and other minerals. To be economically viable for mining, iron ore must contain at least 20% iron. Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%. All iron ore contains ferric oxide and it is from this that iron is ...
Titaniferous magnetite deposits are magmatic accumulations of magnetite and ilmenite. They commonly contain 0.2 to 1 percent V 2 0 5, most of which is concentrated in the magnetite, and they have become the world's principal source of vanadium. These deposits are mostly associated with mafic igneous rocks
The magnetite specimens from this mine have been around for a few years, but because of their brilliance and relatively cubic shape, they have a new standard of quality that other localities find difficult to match. The best from this locality are truly world class for the species. MagnetiteUSAPennsylvania, Berks Co., Morgantown, Grace Mine
Magnetite can be found in the hippocampus. The hippocampus is associated with information processing, specifically learning and memory. However, magnetite can have toxic effects due to its charge or magnetic nature and its involvement in oxidative stress or the production of free radicals.
Magnetite ore and hematite ore are among the four types of iron ore deposits found in this area. In Minnesota, this type of iron ore is mined mainly in the Mesabi Range, one of the four ranges ...
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).
May 01, 2014· A number of minerals pose serious hazards to human beings and the environment.
