How will you separate a mixture of common salt,camphor,and iron filings? Describe the process.

(N/A) $(i)$ Magnetic separation: Pass a magnet over the mixture. The iron filings will be attracted to the magnet and can be separated from the mixture.
$(ii)$ Sublimation: Heat the remaining mixture. Camphor,being a sublimable substance,will change directly from a solid to a gas and can be collected by cooling it on a cold surface (like an inverted funnel),leaving behind the common salt.
$(iii)$ Dissolution and Filtration/Evaporation: Add water to the remaining residue (common salt). The salt will dissolve in the water. Filter the solution to remove any impurities if necessary,then evaporate the water to obtain the common salt.
