Use a magnet to collect all of the iron fillings. Then you make some static electricity with a balloon. Gently rub the statically charged balloon on the contents and it will take everything but the benzoic acid. Now put the rest of the mixture into water. The sawdust will float to the top, scrape them off. The salt will dissolve into the water. The sand will sink to the bottom, filter or seive the mixture. Boil the salty water until all the water has evaporated. Salt residue will be on the sides and the bottom of the pot and can easilly be scraped off. You have successfully separated salt, sand, iron, sawdust, and benzoic acid.
Iron is extracted with a magnet.Salt is soluble in water.After filtration camphor remain on the filter.
Iron is separated with a (electro)magnet.Camphor is extracted with acetone.

by using a bar magnet,because iron fillings are magnetic and hence it gets attracted to that bar magnet
U can separate salt and iron filings from each other by using a bigger magnet . There are other ways too . You can also put both of the mixture in a cup of water and watch as the salt evaporate or disappear . But the iron filings will come to the top . Or spreading the mixture on a table and using a magnet to separate them .

Mix with water, the pass through a filter paper. The salt will be dissolved in the water so it will be removed with the water, leaving the iron filings and gold dust on the filter paper. Leave this to dry then separate off the iron filings using a magnet, leaving behind the gold.

Camphor is a volatile solid i.e. its vapour pressure becomes equal to the atmospheric pressure much below the melting point. But, common salt is non-volatile. Hence, camphor may be very easily separated from common salt by a physical process, SUBLIMATION! props to yahoo answers
Heat mildy. camphor will sublime, collect it separately, cool to get back solid camphor.
a magnet would pull out the iron, and leave the salt.
One way to separate iron nails and salt is by using a magnet. Since iron is magnetic, you can move a magnet over the mixture and the iron nails will be attracted to the magnet, allowing you to separate them from the salt. Another method is to dissolve the mixture in water, as salt dissolves readily, and then use filtration to separate the solid iron nails from the dissolved salt solution.
you can filter it

Take a magnet to get the iron out.Blow the poppy seed out with wind blowing or vacuum cleanerDissolve the benzoic acid in pure alcohol (solubillity max. 2.6 M), filter off.Dissolve the salt in warm water, filter off the 'left-over' sand.(it is possible to reverse the last to steps, but then it is more difficult to evaporate the 'benzoic acid'-tincture, after its final filtration, there will be also some salty water -from the previous step- dissolved in it)
