You canseparate them with a liquid known a sulfuric acid. (it penetrates thought almost anything) Those things that are not soluble can be removed by filters, the sawdust, sand, rocks and iron. The salt and soluble iron will need to be removed chemically. You can evaporate the water and you'll have the salt after removing any iron chemically.

The question didn't say anything about destroying any of the materials! Sulphuric Acid is highly corrosive and would attack the iron and sawdust at least. And your skin if you splash it on yourself.
I'm not sure about the salt but it would not harm the sand (quartz, or silicon dioxide grains).
You can extract the rocks by sieving the mixture; and the iron (filings I presume) with a magnet. That's a start.
Now you can flood the mixture with water and let the sawdust float. Scoop it from the surface of the water, and dry it.
That leaves sand and salt. Dissolve the salt, filter the brine to remove the sand; dry the sand and evaporate the brine to leave the salt.
BTW I hope Dale and I were not helping someone cheat with what look suspiciously like a homework question....

Use a sieve to remove the paper clips and small stones. Heat the remaining solution until the water evaporates (which is recovered by condensation). This will leave the salt behind.
It depends on the brand and packaging, but a standard box of three-inch paper clips typically contains around 100 to 150 clips.
Steel wiredrawing plants manufacture paper clips
Yes, paper clips are typically made of steel which is magnetic, so they can stick to magnets.
A magnet can separate paper clips from marbles in a mixture because paper clips are usually made of metal and are magnetic, while marbles are not magnetic. By using a magnet, you can attract and separate the paper clips from the marbles.

Using magnets or a sieve?
u can put your hand and grad the paper clip.
some how or anther
use a magnet , the paper clips will be attracted to the magnet and the sawdust will not move or u can just pik out the paper clips
Filtration is the most simple method.
Add the mixture of sawdust, sand and salt to water. The sawdust will float and can be skimmed form the surface. The salt will dissolve in the water. The sand can be filtered from the mixture which remains. The salt water solution which remains can be heated and the water will evaporate leaving the salt behind.
Yes, magnets attract paper clips because paper clips are made of a magnetic material like iron. The magnetic field produced by the magnet causes the paper clips to be attracted to it.
It is not possible to give an exact number of paper clips in 1 mole since mole is a unit used for counting atoms or molecules, not larger objects like paper clips. However, 1 mole of paper clips would contain Avogadro's number (6.022 x 10^23) of individual paper clips.
