A Description of Magnetite - Rocks And Minerals 4 U
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.

Magnetite - an overview ScienceDirect Topics
Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral, and not only because it is magnetic.The formula could be written as Fe 2+ Fe 3+ 2O 4, which more precisely designates one of its peculiarities.It contains both ferrous (Fe 2+) and ferric (Fe 3+) ions implying synthesis, growth, and stability within an environment where oxidized and reduced states of iron are present and maintained.

Cornwall Mine (MRDS #10069387) FE, CO
The deposit at Cornwall produced 106,000,000 tons of ore containing about 40% Fe, 0.3% Cu, 1.3% S, 0.001 oz/T Au, and pyrite with 1.4% Co. Cobalt first produced commercially in 1941. Bethlehem Cornwall Corporation reports 400,000 to 600,000 pounds (or 273 MT) cobalt produced as a byproduct of mining magnetite (Vhays et al., 1973).

What Are the Uses of Magnetite? - netinbag
2020-4-7 What Are the Uses of Magnetite? Magnetite refers to the ore of the oxide-type mineral magnetite. Is an equiaxed crystal system. The crystals are octahedron and dodecahedron. The crystal face has stripes. Mostly granular aggregates. Iron black, or dark blue indigo. Streaks are black and semi-metallic. opaque. No cleavage. The fracture is uneven.
