Add the mixture of sawdust, sand and salt to water. The sawdust will float and can be skimmed form the surface. The salt will dissolve in the water. The sand can be filtered from the mixture which remains. The salt water solution which remains can be heated and the water will evaporate leaving the salt behind.

How would you separate gold dust from a mixture of iron filings and salt?
Mix with water, the pass through a filter paper. The salt will be dissolved in the water so it will be removed with the water, leaving the iron filings and gold dust on the filter paper. Leave this to dry then separate off the iron filings using a magnet, leaving behind the gold.

What physical property would be the most useful in the separation of fine saw dust and salt?
Magnetism would be the most useful physical property for separating fine saw dust and salt. However, since neither is magnetic, a process of dissolving the salt in water, filtering out the saw dust, and boiling away the water is necessary.
How do you separate copper from sand dust?
You could sift the mixture through a wire screen sieve which has a mesh small enough to let the sand pass through, leaving the copper on top of the screen.
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.
