Crystallization
(if there is a liquid as well, you would use evaporation and crystallization)
:)
You would have to heat the salt particles to 1413 oC in order to boil the salt (sodium chloride) and change it to the gaseous state.
mix the salt and sand into a glass of water. The sand would settle at the bottom of the glass, and the salt would dissolve into the water. pour off the salt water, wait for the water to evaporate, and you will be left with salt, and sand.
Yes, but the separation would be difficult. It would also be impractical because of the quantity of oil you would get.
Fractional distillation is only useful if the components are liquid, and the separation is based on boiling point. Another, more applicable method would be chromatography, either thin layer, paper, or column.
No. Salt makes the freezing point of water lower and the boiling point higher. The particles of salt get in the way of crystal formation when freezing. They also get in the way of particles trying to escape when boiling.
Yes, crystallization is a method of separation; a very known application is the separation of salt from sea waters.
Salt water is a solution, a mixture not a "separation".

evaporation or boiling!!!
salt and chips
If you think to particles as impurities, non-refinned salt have particles of insoluble impurities.
mix the salt and sand into a glass of water. The sand would settle at the bottom of the glass, and the salt would dissolve into the water. pour off the salt water, wait for the water to evaporate, and you will be left with salt, and sand.
The separation is practically total.
Filtration, sedimentation (settlement), centrifuge, decanting
When salt is mixed with water sodium chloride is dissociated in ions.
evaporation
Yes, these particles are microcrystals of NaCl.
