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.
A solution of sand and saw dust can be separated by filtraton method.
Immerse the mixture in water, agitate and the sand will fall out leaving the sawdust floating on top.
put it in water.
sublimation
Bypicking
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.
You can not separate a mixture of sawdust and sand through filtration process as both of these materials do not pass through the filter paper in the filtration funnel after mixing them in water.
water and a magnet
Place the mixture in water and separate the sand from the water if you want the salt. alow the water to evaporate, and you have salt and sand separated.
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.
pour water in the cup, the saw dust flouts up the sand stays at the bottom

we can separate salt and sand by solving the mixture into water salt is soluble but sand is not .
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.

One direction
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.
Lets say you have mixture of sand and salt. Put your mixture on a filter paper and by using a strong magnet you should be able to separate sand from salt. Using a magnet is a powerful way to separate out one solid from another in a mixture.

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.
