you use a magent
Use a magnet to lift out the iron filings.
The iron fillings are attracted by the magnet and separated from the sulphur powder.
The iron and sulfur react to form the compound iron sulfide.
If you put the magnet near the iron fillings, they will be drawn out by the magnetic pull of the magnet.
Using a magnet would be the easiest way.
fractional distillation
a magnet
Yes you can. You might do it with a magnet.
We can observe small particles of iron and sulfur.
Heating a mixture of sulfur powder and iron fillings will produce Generation of black iron sulfide (FeS) because of insufficient oxidation of sulfur into the iron oxide +3, and Fe2O3 iron sulfide is black, not yellow over iron sulfide (FeS2) ,can be called pyrite. Use iron fillings and sulphur powder and distinguish between these on the basis of: i) appearance i.e., homogeneity and heterogeneity ii) behavior towards a magnet iii) behavior towards carbon disulphide a solvent iv) effect of heat.
you can easily remove iron with magnet. then if you do not care about the sulfur you can set it on fire, and what is left will be pure sand. If you do care about sulfur i don't think i can help you.
When temerature is high enough: Fe + S --> FeS (+ heat, energy)
