Add water to the mixture.
The sand will sink to the bottom, the wood will float to the top and the salt will dissolve in the water.
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.
To separate this mixture, you could first use a magnet to separate the iron filings. Then, you could add water to dissolve the sugar, leaving the sand and sawdust behind. The sawdust can be separated from the sand by filtration.
First heat the mixture; the iodine will sublime and turn to a vapor which can be collected. Then add water to the remaining salt/sand mixture; the salt will dissolve but the sand will not. Finally, evaporate the water to obtain the solid salt.
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.
Since salt is soluble in water then you have to separate the mixture from sand first and this is done by filtration. The sand will be left in the filter paper and the filtererd solution would be that of salt and water. To get the salt you would then have to heat the solution and the water will evaporate leaving the salt behind.Filter Paper

pour water in the cup, the saw dust flouts up the sand stays at the bottom

If all three are mixed together you can separate the sawdust from the group with a Sieve filter with holes smaller than the sawdust, but larger than the sand/salt particles. You could then use another sieve, if the sand and salt particles are significantly different in size,...OR add water to the mix....the salt will dissolve into solution leaving the sand behind. Pour off the water and let it evaporate, leaving the salt behind. Put the mixture of sand, salt and sawdust into a quantity of water: the sand will sink to the bottom, sawdust will float and salt will dissolve. Skim off (and dry) the floating sawdust. Pour off the water containing the dissolved salt. This is then heated to cause all the water to evaporate (leaving behind the salt). The remaining residue in the original container (wet sand) can now be dried off with heat.
To separate a mixture of salt and sand, you can use the method of dissolving the salt in water and then filtering the sand out. If the mixture consists of iron filings instead of salt, you can use a magnet to attract and separate the iron filings from the sand. This method works since iron is magnetic while sand is not.
If the particles are each of different size, these compounds may be separated based on two selective filtrations using appropriately-sized sieves. If this process is not possible, than separation may be accomplished by dissolving the salt in another polar solvent such as liquid ammonia or methanol (about 1 or 2 grams of NaCl will dissolve per 100mL of these solvents). The sand and sawdust could then be separated using their density, as the sawdust would float and the sand would sink. Evaporation the solvent would yield the solid salt.

To separate sand from salt and pebbles, use a sieve to filter out the larger pebbles first, then add water to dissolve the salt and separate it from the sand through filtration. To separate salt from sand and pebbles, dissolve the salt in water and then evaporate the water to obtain the salt crystals, leaving the sand and pebbles behind. To separate pebbles from sand and salt, use a sieve or filtration to separate the larger pebbles from the sand and salt mixture.
Put the mixture in water and wait for all of the salt to dissolve. Then filter out the sand and wait for the water to evaporate in the sand/water solution to get the sand and salt separately.
