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 formula for magnetite is Fe3O4. Magnetite is a mineral found in nature in the form of iron oxides. This ore is a natural magnet.
