First put the mixture in a colander and separate the salt and pepper from the pebbles. Then put the salt and pepper in water and stir it to dissolve the salt. The pepper will not dissolve, and you can remove the pepper. Then allow the water to dissolve and you will be left with the salt.
Miners used the technique of panning to separate gold from sand and pebbles in running water. They would gently swirl a pan containing the materials in water, allowing the gold to sink to the bottom while the lighter materials were washed away.
A typical density for black pepper is 550g/l. This really depends on what kind of pepper you are talking about. Here is a useful formula to find out the density of your method. D= M/V (Density equals Mass divided by Volume) You can find the Mass by weighing the pepper on a scale. You can figure out the approximate volume by measuring the pepper in different ways (depending on its size). Once you have the 2 results, you can divide the Mass of the pepper by the Volume of the pepper. The result would be the Density of the pepper.
Use a magnet to separate the iron, Add the reaming mixture to water, the salt will dissolve, the pepper will float and the sand will sink- separate the pepper from the surface, filter the solution to retrieve the sand then evaporate the water to get the salt
place or pass through a grating whose opening size is larger than the soil but smaller than the stones that you want to keep. If you want to keep the soil, then pass the combination through the same grating and make sure the soil ends up in a container of some kind.
it's a mixture !
your eyesight
Vibrations should make the lighter pepper rise to the top.
You would screen out the larger rocks. Build a wooden frame, and use some screen that would exclude the rocks, but which would allow the pebbles to flow through. What he said works, but I consider pebbles to be small, kind of round, smooth stones. You could do what he said, or you could rake them, or depending on your situation, using your hands might be better, if you only need a few of them.
you separate those items by weight, appearance, and density
Cracked pepper is a peppercorn that has been broken apart or "cracked" The pepper you would have on your table is more ground up and finer in consistency.
pepper actually floats only some goes to the bottom in a water solution so after that you would need to filter the pepper and sawdust because it is larger and then evaporate the water.
you can seperate it by using a screem
It would be a good idea to have pepper grinders because sometimes you may need to grind up pepper due to not having it already ground up at the table.

to separate salt and water you can put it out side and let the water evaporate or to speed things up you can put it on the stove.
A mixture of pebbles and water would be heterogeneous.
