Firstly, sift the mixture to separate the gravel from the sand and salt.
Now place the sifted mixture into water. The sand will sink to the bottom and the salt will eventually dissolve.
Pour this watery mixture through filter paper to catch all of the sand.
If you want the salt back in solid form, simply boil the water.
To separate sand, gravel, and water, you can use a filtration method. Pour the mixture through a filter such as a sieve or cloth to separate the sand and gravel from the water. The water will pass through while the sand and gravel remain on the filter.
You could use a magnet to separate the iron fillings from the mixture, as iron is magnetic while the other substances are not. Next, you could use water to dissolve the salt, allowing you to separate it from the sand and gravel mixture. Finally, you could use a sieve to separate the remaining sand and gravel mixture based on particle size.
A sieve or a mesh screen can be used to separate sand from gravel. The mixture is poured onto the sieve, and the smaller particles like sand will fall through, while the larger gravel particles will remain on top.
With a fine mesh sieve.

As salt is soluble in water, mixing salt and sand in water would result in solid sand, and salt water. When poured through a coffee filter, the sand would remain in the filter, while the salt water would flow through. After letting the water evaporate, salt would remain. You will be left with the two separated solids.

Sand and gravel can be separated by sifting them through a mesh, that will allow the sand to fall through, but will hold back the gravel.

1. Put the mixture of gravel and salt in water. 2. Salt is water soluble, gravel not. 3. Filter: the salt is in the solution.
You can separate sand and gravel using a sieve, as the smaller sand particles will pass through the sieve while the larger gravel particles will not. You can also separate rice and beans with a sieve, as the smaller rice grains will fall through while the larger beans will be retained.

A simple method is sieving.
I think road salt it made of salt, gravel and sand. The salf lowers the melting point of the snow/ice, so therefore melting it, and the sand and gravel give a car grip.
