All you have to do is put a magnet over the mess of sawdust and iron fillings and the iron fillings will get stuck to the magnet. Then their seperated
you would use the iron's magnestism to extract it with a magnetic tube
Iron fillings can be extracted with a magnet.
Iron is magnetic; so, the iron filling is pulled/ is attracted to the magnet. The sawdust is not magnetic, so it will stay where it is, and will eventually be separated from the iron and the magnet.
Use a magnet to separate the iron filings, filter the remaining sawdust and sugar water solution, evaporate the water from the sugar water solution.
The easiest way is with a magnet. It'll attract the iron and not the copper. If you're on a higher budget, the difference in the melting point could help.

Simply use a magnet. If the magnet is strong enough, you can simply hold it just above the sawdust and the fillings will come zooming out and onto the magnet. If it is kinda weak, put it in the sawdust and remove. Either way, the fillings will be on the magnet. (Sorry,I didn't realize that I had entered this without logging in. This is really from Chickadee1999)
Use a magnet to seperate the iron. Then, add water to dissolve the salt and float the sawdust. Skim off, sieve or filter the solution to seperate the sawdust. Let the water evaporate, leaving the salt behind.
you an use a magnet to get the iron fillings out
use a magnet
A magnet
use a magnet :)
Use an electromagnet.
Very easily, put a magnet on them it will attract the iron but not the aluminium.
use a magnet
Use a magnet.
With a magnet : only iron will be attracted.
