Place the mixture in water. You recover the iron once the salt dissolves. Then allow the water salt mixture to dry and allow salt crystals to reform.

you an use a magnet to get the iron fillings out
by using carbon disulphide

Iron fillings can be separated: - with a magnet - after the dissolution of the mixture, by filtering
The easiest way is with a magnet. It'll attract the iron and not the copper. If you're on a higher budget, the difference in the melting point could help.
Use a magnet to lift out the iron filings.
Well, you have to be very specific about this question. Substances can separate in a compound mixture, such as chex mix, by pulling the stuff right out. Other stuff, maybe not.
A heterogeneous mixture is made of different substances that remain physically separate.
To separate out the iron fillings, run a magnet over the mixture of iron fillings, sand and water. As iron is a magnetic material, it will stick to the magnet thus allowing you to take it out. Then, run the mixture over a filter funnel with filter paper. After the filtration, the filtrate would be water and the sand would be stuck on the filter paper.
When substances combine and retain their own properties, the result is a mixture.
