Question

name two important magnetic ores​

Answer 1

Answer:

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, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.

Answer 2

Answer:

The most important magnetic carriers in rocks and soils are iron oxides, iron-titanium oxides and iron oxyhydroxides. Magnetite (Fe3O4) and related ferrimagnetic minerals like titanomagnetite and maghemite (γ-Fe2O3) are the minerals, which have the largest saturation magnetization.
