If you are asking how you can seperate salt, pepper and sand, i can help you. To seperate these, you will use the differences they have in their chemical properties. To start, you could mix them all in water. The salt will disolve in the water and the sand will sink to the bottom because it isn't disolvable in water. The pepper should stay on top of the water. You can then filter the pepper from the water through use of a filter paper. You can then boil the water until it vaporizes. This will leave you with the salt.
Hope this helps. And this should work, but it's been a year since i have done the lab. If you are looking for a simple answer, just say that you seperate them by using the differences in their physical and chemical properties.

Pepper floats, salt dissolves and sand does neither. So put the lot in enough water to make the water cover it all to about 3cm, and stir the mix . Scoop the floating pepper of the top. Put the salt, sand ands water solution into a paper filter. the salt water will go through, but not the sand. Evaporate the water and you will have each part seperate again.

Umm.. i could say combination the sand and salt mutually and positioned the salt in heat/warm water and enable it dissolve the salt.... then filter out the liquid out leaving the sand in the back of, or making use of a sieve to pour the water/dissolved salt via and leave the sand in the back of and set the sand aside (rinse sand to get all salt out), and then evaporate the water and it will leave the salt in the back of. ta-da!

It'd be a lot easier to answer your question if you explained what you wanted to know.
What why can you separate? Why, 42, of course.
