From what?
If from water, evaporate the water.
If you're talking sodium from chlorine, http://wiki.answers.com/Q/Can_you_separate_the_sodium_and_chlorine_in_sodium_chloride
Evaporate water, then the salt would be separated.

Boil the water off. It leaves the salt behind.
A possible hypothesis could be: "If salt is mixed with water and the solution is frozen, then the salt will not separate from the water, as both salt and water will freeze together into a solid."
I guess you could use filters.
Yes it can be used to evaporate the water which will leave the salt
Put them in water. Sugar dissolves, sand remains Filter the solution to separate sand and salt. Evaporate solution with dissolved salt to get salt back
To separate sand and salt, you can use the process of filtration. First, add water to the mixture to dissolve the salt. Then, pour the mixture through a filter to separate the sand, which will be left behind, from the salt solution that passes through. Finally, evaporate the water from the salt solution to retrieve the salt.
No, it cannot separate salt from a salt solution. This is because salt is soluble in water.
Clearly, a magnet will separate the iron filings from the mixture, leaving just the salt and sand. Then you could run water through that to dissolve the salt, leaving just the sand. If you collect the water and evaporate it, you'll be left with the salt.
how do you separate aluminum powder and salt
Separate the sand grains using a fine mesh. Separate salt from the water by using evaporation (leaving the salt crystals behind), and condensation (turning the evaporated water vapor back into a liquid).
