The salt should be an Iodide salt. Put the iodide salt into concentrated sulfuric acid. This will oxidize iodide to elementary Iodine.
I- + H2SO4 ----> I2 + SO2 + H2O + HSO4-
Another way is treating iodide salt with Chlorine, which will oxidize iodide to iodine and chlorine will be reduced to chloride.
2 I- + Cl2 ----> I2 + 2 Cl-
heat the mixture iodine will sublime collect the iodine vapour separately and cool
i think, perhaps cyrstalization or centrifugation.
First heat the mixture; the iodine will sublime and turn to a vapor which can be collected. Then add water to the remaining salt/sand mixture; the salt will dissolve but the sand will not. Finally, evaporate the water to obtain the solid salt.

how can we separate iodine and napthelena
Regular "table salt" is a compound of sodium and chlorine. Iodine is often added to it before it's sold, as a dietary supplement to protect against the dangers of iodine- deficiency diseases, but iodine is a separate element that's not involved in the composition of pure table salt. But there are "salts" of other elements too, and they include things like silver iodide and potassium iodide, in which iodine is part of the chemical compound.
we can separate them by sublimation as iodine sublimes on heating.
No, salt is mainly Sodium. Iodine is added to salt to prevent iodine deficiency.
Yes. Sea salt contains iodine.
iodine crystals are black, table salt crystals are white.however I doubt that was your question. I think you are referring to iodized table salt. there are no iodine crystals in iodized salt, instead they add sodium iodide to the table salt. sodium iodide crystals are indistinguishable visually from the sodium chloride crystals of table salt.the only practical way to separate sodium iodide from sodium chloride is the very tedious repetitive process of dissolving the mixed salts and performing fractional crystallization of the solution.
with alot of hard work that's way to advanced for your mini mind
If I had a large quantity of a mixture of iodine and salt and wanted to separate them, I'd probably just use heat. Iodine turns into a gas at a relatively low temperature (below 200 degrees Celcius), at which temperature sodium chloride is still stubbornly solid.Iodine is also considerably less soluble in water than salt is, so if you don't care about a small iodine impurity in the salt you could just add water and pour off the supernatant solution.
