You can add water to this mixture, which will dissolve the salt but not the chalk. Decant the water, then boil it away, and you will be left with salt.

Salt is much more soluble in water than chalk is.

How do you separate a mixture of sand salt chalk dust and amp iron filings.?

First remove iron filings with a magnet. That leaves sand, salt and chalk dust. Add water which dissolves the salt, and filter leaving the sand and chalk dust on the filter paper. Put that back in water and add acid to dissolve the chalk dust (CaCO3) leaving the sand as a solid. Filter to obtain the sand. The chalk dust will now be in the acid as CO2 and H2O and the Ca salt of the acid.
