collect the iodine vapour separately and cool
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.
To separate salt and iodine, you can use sublimation. The iodine will sublimate at room temperature, leaving the salt behind. To purify the iodine further, you can re-sublimate it by heating it gently and collecting the vapor to form pure iodine crystals.

One method to separate iodine crystals from a mixture of iodine and sand is by using sublimation. Heat the mixture, and the iodine will sublimate (turn into gas) leaving the sand behind. The iodine gas can then be collected and cooled to form iodine crystals.
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.

You can separate a mixture of iodine solid and sodium iodide by using the difference in solubility of the two compounds. Since sodium iodide is soluble in water while iodine is not, you can dissolve the mixture in water to dissolve the sodium iodide, leaving the solid iodine behind. The two can then be separated by filtration.
To separate a mixture of salt and rice, you can use the method of dissolving the salt in water. When you add water to the mixture, the salt will dissolve while the rice will remain intact. Then, you can filter the mixture to separate the rice from the salty water. Finally, you can evaporate the water to obtain the salt.
You Can't!
By heating it at low temperatures.
First add water to mixture the ammonium chloride will dissolve in the water but the iodine does not. Filter out the iodine using filtration then use evaporation or distillation to obtain the ammonium chloride.
To separate a mixture of salt and sand, you can use the method of dissolving the salt in water and then filtering the sand out. If the mixture consists of iron filings instead of salt, you can use a magnet to attract and separate the iron filings from the sand. This method works since iron is magnetic while sand is not.
