I would add enough water to dissolve all of the salt. Then pass it through a strainer to collect the gravel.

The gravel and sand filter out smaller particles from the water
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.
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.
Filtration can separate a mixture of fine sand and coarse gravel by using a filter with holes large enough to allow the gravel to pass through while retaining the sand. In this case, the filter would ideally allow the gravel to pass through freely, while the sand remains trapped. Thus, the appropriate answer is "sand but not gravel."

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.
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.

With a fine mesh sieve.
You run the sand and gravel over different size screens depending on how many sizes you wish to sort the gravel into. In most large gravel pits, a deposit is sucked up with a pump (with water) through metal pipe up to a steel tower.Using gravity the sand,small pea gravel and larger gravels are separated. In most gravel pits the water turns green over time because of the Iron in the deposits.
A simple method is sieving.
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.
One way to separate sand from gravel is by using a sieve or screen with appropriately sized mesh openings. Pour the mixture onto the sieve and shake gently to allow the smaller sand particles to fall through while retaining the larger gravel particles. Alternatively, you could use a method called sedimentation - by pouring the mixture into water, the gravel will sink while the sand floats, making it easier to separate them.
