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.
please help me find the answer to separating salt from soil
by distillation.
if you do not need to preserve the water, just boil it away.
if you need to preserve the water, use a condenser.
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
distillation method
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.
You can simply separate salt and water by distillation method.
It magnetism
The process is distillation.
use fiter paper
Probably the simplest method is to dissolve the salt in water, filter the sulphur out (then evaporate the salt solution to recover the salt if desired.)
Distillation would be the most effective method. In this manner, you can obtain both the distillate and the residue.
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.
One way to separate iron nails and salt is by using a magnet. Since iron is magnetic, you can move a magnet over the mixture and the iron nails will be attracted to the magnet, allowing you to separate them from the salt. Another method is to dissolve the mixture in water, as salt dissolves readily, and then use filtration to separate the solid iron nails from the dissolved salt solution.
