Use a magnet to pick up the iron. Then add water. The sugar will dissolve and run out as syrup, and the sand will remain.

water and a magnet
Use a magnet to remove the iron, then pour what is left into water. The sugar should dissolve. pour the solution through a sieve to remove the sand and gravel. A fine sieve can be used to separate the gravel and sand.
it will get on the iron if you try to separate sand will be on the iron
Magnets would remove the iron. sugar is water soluble now you have sulfur and sand mixed. Apply heat sulfur will burn before the sand.
Soluble in water, sand is not.
Use a magnet to attract all the iron out of the sand
to separate the mixture of sand and sugar:- first: you can mix water in it and after mixing you can separate the water and sand. and after that you boil the water until whole water is evaporated and you get sugar and sand separated. second: if difference b/w size of sugar and sand particle you can use met to separate them.
Separate the sugar solution from the sand by passing the solution through a coarse paper filter. Or syphon off the sugar solution, leaving the sand behind.
What is special about iron filings? Anything with iron in it has this property... magnets are attracted to iron! Magnets do not attract sand. You can use a magnet to separate iron filings from sand.
Remove the iron filings with a magnet. That will leave the sugar and sand left. Then use a fine sieve to remove the sand. Or if those particles are too much the same size, then add water to the mixture and then use a filter. The sand will stay behind on the filter. You now have to remove the water. You can do that by letting it evaporate.
Iron can be separated from sand using a (electro)magnet.
A magnet will cause the iron to adhere and separate. Or adding water will dissolve the sugar and the iron can be filtered out and then the water evaporated from the sugar.
