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.
Magnetite is Fe3O4.
The diaphaneity of magnetite is opaque.
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.
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.
