It is a mixture of an Iron compound and a rock substrate. Iron ores are usually rich in Iron Oxides (a compound) and minerals. Since the iron is not chemiically bonded to the mineral substrate it is a mixture.
Iron ore is a mixture.
Iron sulfide is a compound.
FEO2 means Iron (Fe) and 2 oxygen (O) atoms.
Iron is an element; it cannot be broken down into smaller atoms. Every atom in iron is a iron atom so it is homogenous.
Ores such as iron oxide is a compound and not a mixture due to two reasons: i. iron atoms being chemically bonded (not physically mixed) to oxygen atoms forming iron oxide; ii. the separation of iron from its oxide requires a chemical reaction.
Iron atoms are not chemically joined with another substance in a mixture. Chemical reactions are needed to separate them in a compound.
"Atoms" of the compound iron oxide do not exist, but the compound contains iron and oxygen atoms, both in the form of ions.
stuff
in its pure form, iron is an element, but that may not be what you are referring to.... if you have iron oxide (rust), this is a compound of iron and oxygen.
"Atoms" of the compound iron oxide do not exist, but the compound contains iron and oxygen atoms, both in the form of ions.

To reduce a compound is to remove oxygen from it. Iron oxide can be reduced to iron by removing its oxygen atoms.
Fe2O3
There are two atoms of iron and three atoms of oxygen in the compound Fe2O3. The mass percent of iron is 69.943%
Rust is a compound of iron and oxygen.
These compounds are iron oxides as FeO, Fe2O3, Fe3O4.Rust.
