1. Run a magnet over the mixture. Iron will be attracted to the magnet, hence allowing it to be separated.2. Sublime/crystallise the ammonium chloride through heating.
3. Dissolve what you have left in water. Now filter the mixture through a filter funnel with filter paper. The residue on the filter paper would be sand.
Gently heat - ammonium chloride will sublime on a cold solid surface
One way is to slurry the solid mixture with water. The ammonium chloride will dissolve and the naphthalene will not. Ammonium chloride can then be recovered by evaporating the water solution of it that is formed.

A mixture of ammonium chloride and potassium chloride can be separated using the process of sublimation. You must also note that both these substances are sublimable. Well this technique is quite feasible in this case as the sublimable temperatures of ammonium and potassium chloride differ widely. Between the two, ammonium chloride has lower sublimable temperature. Therefore, it sublimes first followed by potassium chloride.
Sodium chloride and ammonium chloride can be separated either by sublimation or filtration or crystallization. Sublimation can be found on this site ------------ http://www.lenntech.com/Chemistry/sublimation.htm. I personally think that this method is the easiest.

Heating the mixture ammonium chloride is decomposed after 315 oC.

By the process of sublimation.
Ammonium chloride is soluble in water and copper oxide not; dissolve the mixture and filter.
Ammonium chloride is soluble in water, sulphur isn't. So mix the mixture with water and filter out the sulphur. Now evaporate the filtrate to obtain the ammonium chloride and permit the sulphur to dry.
Do Not Kow
Because ammonium chloride can be removed from salt by sublimation (at a given temperature).
none
no because both sublime on heating
first add water to mixture the ammonium chloride and barium chloride dissolve in the water but the iodine does not. filter out the iodine using filtration then use fractional crystallization to separate the ammonium chloride and barium chloride and water
I suppose that the best method is a repeated crystallization/recrystallization process.
