1st answer:filter the soil through filter paper
2nd answer: incorect information above
new answer: If it is literally salt poured over the soil you could use a centrifuge. :)

3rd answer: Answer 1 is on the right track if the quantity is small. Use water to dissolve the salt then filter the solids (mud!) from the brine.
At a larger scale there such as in the garden there is probably little you can do. Although wasteful of water, drenching the soil will dissolve the salt you can't simply scoop up, and the solution will leach down into the ground and eventually become harmless. If the ground is dry, scoop up the top layer of soil and salt, then dissolve and wash the salt away.
Boiling off the water from a salt solution will separate the solid salt and water (which can be collected by a condenser).
Hold a magnet over it and the iron will fly out of the salt and stick to it, and the salt will stay there.
settling
Allow the water to evaporate, leaving behind the salt would be effective for separating salt and water in a mixture.
<p>You can separate the sand by filtration, but still the salt (mainly sodium chloride) is dissolved in the water. Then, you can separate the salt from water by distillation. The liquid you collect after water vapor is chilled is distilled water. You can use other methods to separate sand as sedimentation (usually slower than filtration) and salt as reverse osmosis.<p>
You can simply separate salt and water by distillation method.

EVAPORATION
One commonly used method to separate aluminium pieces from salt is by using a magnet. Since aluminium is not magnetic, the magnet can attract and separate the aluminium pieces from the salt. Another method is to dissolve the salt in water and then use filtration to separate the larger aluminium pieces from the saltwater solution.
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.

You can separate salt and water by using the process of evaporation. Simply heat the mixture until the water evaporates, leaving the salt behind. This method works because salt does not evaporate with the water.
To separate a mixture of salt and rice, you can use the method of dissolving the salt in water. When you add water to the mixture, the salt will dissolve while the rice will remain intact. Then, you can filter the mixture to separate the rice from the salty water. Finally, you can evaporate the water to obtain the salt.
One method to separate sand from salt is by dissolving the mixture in water to dissolve the salt, then filtering the solution to separate the sand from the saltwater. Another way is to use a sieve to physically separate the larger particles of sand from the smaller particles of salt.
Distillation would be the most effective method. In this manner, you can obtain both the distillate and the residue.
One common method to separate peas and salt is to use the property of solubility: dissolve the mixture in water, then filter the solution. The salt will dissolve in the water, while the peas will remain and can be filtered out. Alternatively, you can use a physical method like hand-picking the peas from the salt.
A method is repeated processes of crystallization/recrystallization, for a supplementary refining.But it is a nonsense in your question: salt or pure salt are both sodium chloride, supposed to be pure.
