Needs to be done in a couple of stages:
1 - Magnet works to separate the iron from other components.
2 - Sugar and sand have very different densities (and solubility)

Not rocket science, its pretty simple if you remember that each substance is affected or changed by something that doesn't affect the other substances.
What will affect iron filings (not fillings) and not the sand or sugar? A magnet.
What will affect the sugar but not the sand? Water.

you can use a magnet to get the iron out, then pour the sugar and sand in water and stir until the sugar dissolves, use a strainer to swparate the sugar water and sand then evaporate the water. you will be left with iron from the magnet, sand from straining, and sugar from evaporating.

First off, you should be doing your own homework instead of cheating.
This is an OLD puzzle.
Hints:
* Iron is magnetic.
* Sugar is soluble in water
