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....

Yes, paper can be made from sawdust, which is a byproduct of wood processing. The sawdust is processed into pulp, typically through mechanical or chemical methods, to separate cellulose fibers. These fibers are then combined with water and other additives to create a slurry, which is formed into sheets and dried to produce paper. Using sawdust for paper production is an eco-friendly way to utilize waste material and reduce the reliance on traditional wood sources.
The best method to separate paper clips from a mixture of salt and pennies is to use a magnet. Since paper clips are made of metal, they will be attracted to the magnet, allowing you to easily remove them from the mixture. After removing the paper clips, you can then dissolve the salt in water, leaving the pennies behind, as they do not dissolve. Finally, you can filter the solution to retrieve the salt and have the pennies separated.
A sieve or a screen would be the best tool to separate a mixture of marbles and paper clips. The marbles, being larger and round, would not pass through the holes of the sieve, while the paper clips, being smaller and flat, would fall through. This method effectively utilizes the size difference between the two items for efficient separation.
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.
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.

To separate plastic paper clips from metal paper clips, you can use a magnet to attract the metal clips, as they will stick to the magnet while the plastic ones remain unaffected. Alternatively, you can manually sort them by hand, grouping the plastic and metal clips into separate containers. If you have a larger quantity, consider using a sieve or screen to separate them based on weight, as plastic clips are generally lighter than metal ones.

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.
