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.
Weigh each sample and then make a solution of coffee, sand and water. First of all, we have to filter the solution with the help of filter paper so all the water will pass through the paper and as a filtrate we will have coffee and sand. Take the filtrate and let it dry. Secondly, once the filtrate is dry take a strong magnet and scan across, underneath the filter paper. This will separate all the sand on one side of the filter paper. Finally, record the mass of each component after the experiment.
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.
Physical because you are not changing the substance.
Sift to separate everything from the gravel. Then use a magnet (If needed) to pull out the iron. Now you are left with sand and salt. Dump this mixture into water. The sand should sink to the bottom. The salt should dissolve. Pour the mixture through filter paper to catch the sand. Boil the water and it will evaporate. Now you are left with salt.
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.
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.
The gravel and sand filter out smaller particles from the water
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.

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.
With a fine mesh sieve.
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.
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.
with fillter paper
A simple method is sieving.
With a coffee filter
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.
