Use a magnet.
Sand and marbles would not be a solution. A solution has a solute (a solid) and a solvent (a liquid). You must also not be able to just separate the two. Sand and marbles would not be a solution because you can simply pick out the marbles, and there is no solvent!
Hover a magnet over the mixture.The iron filings will be attracted to it.A mixture of sand and camphor will be left. Then,separate the mixture of sand and camphor by using sublimation.
It is sand-I did the question
Use a magnet. The magnet will remove the iron filings form the sand.
For the nails, you can use a magnet. You can separate the marbles and corks by putting it in water, wood floats and marbles don't.
it will get on the iron if you try to separate sand will be on the iron
You have to pick them up

Pour into a sieve or colander, the sand will pass through the open mesh, leaving the larger marbles trapped inside the sieve.
Use a magnet to attract all the iron out of the sand
What is special about iron filings? Anything with iron in it has this property... magnets are attracted to iron! Magnets do not attract sand. You can use a magnet to separate iron filings from sand.
Iron can be separated from sand using a (electro)magnet.
In solution, the salt will be dissolved in the water, the sand and iron will settle to the bottom of the container. Separate out the water, evaporate the water and the salt will remain, separate the sand and iron filings with a magnet.
We can use a magnet. It will attract the iron and pull it from the sand.

because the iron can be picked up by a magnet
With a magnet : only iron will be attracted.
