Magnetite is a naturally occurring magnetic mineral composed of iron oxide (Fe3O4), whereas pyrolusite is a mineral composed of manganese dioxide (MnO2). Magnetite is black or gray in color, has a metallic luster, and is magnetic, while pyrolusite is typically black or dark gray and has a dull to submetallic luster. Magnetite is commonly used in industries like mining and construction, while pyrolusite is used in the production of dry cell batteries and as a pigment in ceramics and glass.

The diaphaneity of magnetite is opaque.
The chemical formula of magnetite is Fe3O4.Iron: 74,41 %Oxygen: 27,59 %
Magnetite belongs to the oxide mineral group. It is a primary iron oxide mineral and has a chemical formula of Fe3O4.
magnetite is harder than galena. Magnetite has a hardness just under glass, so around 5. Galena sits at around 4 on mohs hardness scale
Pyrolusite (MnO2) doesn't rust.
no
it is essential for steel making.

The most known mineral is pyrolusite - MnO2.
Magnetite is the magnetic iron oxide mineral. It is a black or brown mineral with a chemical formula Fe3O4, and it is a common iron ore mineral found in many rocks and soils around the world. It is known for its strong magnetic properties.
Pyrolusite is a manganese oxide mineral, that has yet to cause any fatalities. It could kill you if you grind it very fine and inhale it, or eat enough of it, or drop a block of it on your head, but other than that it's not much of a hazard to anybody.
The diaphaneity of magnetite is opaque.
Magnetite is Fe3O4.
Magnetite was found on the mountain of Mount Ida.
The formula for magnetite is Fe3O4. Magnetite is a mineral found in nature in the form of iron oxides. This ore is a natural magnet.
Magnetite is classified as a mineral, not a rock.
