I guess you could add fluorine to it to get rid of salt (6NaCl + F2 -> 2Na3F + 3Cl2), but only if sodium fluoride turns out to be a solid. If you kept this mixture in one of those complex vaccuum thingys, then you could get salt and fluorine back.
After that, just add water, take out the wet sand, and dry both the sugar water and the sand.
P.S. Allison's got a point. We actually don't know whether or not it's fine particles of each. If it happened to be rock salt and sugar cubes, we could just pick them out.

Separating the sand from the (salt and sugar) is easy since salt and sugar both dissolve in water but sand doesn't but that only gets you part way there.
How about another way? Maybe think about the densities of these materials and different liquids that do not dissolve any of them... hmmm

Ole Charlie's answer was good, but the sand might be fine enough that the salt and sand can't be sifted apart.
I suggest heating until the sugar drips out, then dissolving the salt in water. Strain out the sand, and then let the saline solution evaporate, leaving you with salt.

Assuming they have different particle sizes, you could easily use a sieve device which has multiple plates with different mesh screen sizes.
If not, add water to dissolve the sugar / salt and filter off the sand. Then heat the water to carmelize the sugar and pour off the remaining salt water. Then boil off the water and salt will remain

Heat the combination until the sugar melts and drips out. Sift the salt through a strainer, and you have sand left.

add water until sugar and salt dissolve. filter the mixture - you got sand separated out.
boil away the water. you have mixture of salt and sugar. add lots of paraffin. now the sugar dissolved, salt didn't. filter this. you have salt in the filter, sugar in solution.

You can't heat the sugar because it decomposes upon heating. It does not melt!
