you would use the iron's magnestism to extract it with a magnetic tube
place a magnet in a baggie and use it to pick up the iron fillings
using magnet for iron fillings and water for the sawdust to float, thus, the sugar will be left, let it dry
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.
Use a magnet to lift out the iron filings.
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.
Iron fillings has the property of being magnetic, so you could pass it through a magnetic drum to remove it leaving sulfur and sand. Since sulfur is a solute it will dissolve in water leaving sand and forming a solution. You can then pass that through a filter separating the sand and the solution containing water and sulfur. Now you can put the solution in an evaporating basin to evaporate the water leaving the sulfur.
Filtration or centrifugation.
Very easily, put a magnet on them it will attract the iron but not the aluminium.
With a magnet : only iron will be attracted.
Since lead iodide is insoluble in an aqueous solution, you could filter it out using a funnel and filter paper.

please state what kind of solution you wanna separate, is it solid, liquid or gas?you could separate solutions by this methods:pickingfreezing or chillingevaporationdistillaionfiltrationdecantationand etc.(note:thre are many more methods to sperate a solution)
If all three are mixed together you can separate the sawdust from the group with a Sieve filter with holes smaller than the sawdust, but larger than the sand/salt particles. You could then use another sieve, if the sand and salt particles are significantly different in size,...OR add water to the mix....the salt will dissolve into solution leaving the sand behind. Pour off the water and let it evaporate, leaving the salt behind. Put the mixture of sand, salt and sawdust into a quantity of water: the sand will sink to the bottom, sawdust will float and salt will dissolve. Skim off (and dry) the floating sawdust. Pour off the water containing the dissolved salt. This is then heated to cause all the water to evaporate (leaving behind the salt). The remaining residue in the original container (wet sand) can now be dried off with heat.

there are many techniques to it. The best can be heating the solution till the time the solution gets evaporated and it leaves behind the salt.
Distillation
Boil the water off. It leaves the salt behind.
