Question

How do we seperate a mixture of common salt , camphor and iron filling

Answer 1

put the mixture in bowl use magnet to separate iron fillings. Use sublimation process to separate camphor and finally put remaining in water use evaporation method to get salt

Answer 2

Iron is magnetic and the other two not, which means a magnet could be used to attract the iron filings out of the mixture, leaving the salt and sand. Salt is water soluble, while sand is not. This means the two can be mixed in water and stirred. The salt will dissolve and the sand will not.
