You would use a filter in this case a grate bigger than the the sand yet smaller than the gravel that you could probably buy at your neighborhood grocery store or online.
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.
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.

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.
If we need to separate sand and gravel, we simply use the size of the material and a mechanical contraption to do the separating. A screen with mesh of the proper or appropriate dimensions will sieve the particles nicely. The sand will fall through the mesh piling up underneath it, and, if the screen is tilted, the gravel will bounce its way down and off the screen into a separate pile.
One method to separate sand and gravel is using a sieve or screen with appropriately sized openings. The mixture can be poured onto the sieve and shaken to allow the smaller sand particles to fall through while the larger gravel particles remain on top.
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.
Gravel is typically heavier than sand, and therefore gravel would be heavier than both clay and sand. This is because gravel consists of larger-sized particles and has a higher density compared to clay and sand.
