Iron filings may or may not be pure. The ones used in experiments with magnets may not be pure iron. Most iron filings may have a few impurities. But iron (Fe) filings that are reagent grade will be very pure iron metal.
Yes. Its called Iron. Just because the iron was filed, it was a physical change only. If it rusted it would require a name change because that is a chemical change.
Sulfur and iron filings together are a mixture.
Carbon disulfide can be used to separate a mixture of iron filings and sulfur. This is because carbon disulfide can be used to dissolve sulfur, thus leaving you with the iron filings.

I would separate copper strands and iron filings by using a magnet. The iron is magnetic, but the copper is not, so the magnet picks up the iron, but leaves the copper behind.
Iron sulfide
pure substance
Iron is a chemical element; sand may be a compound or a mixture.
compoundIf the iron fillings are pure, they contain only one type of atom (all the atoms have the same number of protons). Thus, the filings would be a sample of the element iron. If the filings are rusty, then they would contain compounds (iron oxides).
Iron filings just means metallic iron, shredded into little bits. It's an element, not a mixture.
Copper filings are not attracted to a magnet, as iron filings are.
Iron filings may be pure elemental iron, it depends on the source of the iron.
Iron fillings are pure iron - until they start rusting. So their formula is Fe.

Sulfur and iron filings together are a mixture.
Iron is an element (can't be divided into two things), although steel is iron mixed with things like carbon, vanadium, manganese, chromium or tungsten. True iron filings are just little shavings of iron, but steel is often used. The extraction and processing of iron ore utilizes the magnetic property of iron, so almost all iron used already has a magnetic polarity "built in".
