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.
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.

To separate iodine from sand, the mixture can be dissolved in water since iodine is soluble in it, while sand is not. Once the iodine is dissolved, the solution can be filtered, leaving the sand behind on the filter paper. The iodine can then be obtained by evaporating the water from the filtered solution.

Add sufficient water to dissolve the ammonium chloride. Neither the iodine nor the sand will dissolve.Filter out the solids.Evaporate the ammonium chloride from the solution.Heat the solids gently in a retort to sublimate the iodine and recover it.
Well every school kid knows about the 'cold finger' separation technique. Iodine changes from a solid straight to a gas when heated. It sublimes. So heat the sand/iodine mixture in a pyrex tube or flask which has a 'cold finger' inserted. The hot iodine gas will rise, hit the cold finger and form pure solid iodine crystals on the cold finger. Collect from the finger. This really is bog standard school kid chemistry.

Iodine is not contained in Sodium Chloride, so can not be removed from it. I am thinking you wish to separate a mixture of Iodine and Sodium Chloride. Heat the mixture to 114C and the iodine will melt. Iodine can be vaporized and distilled. Under certain conditions, Iodine can react with other chemicals to create unstable explosive compounds. So be careful out there.

A compound containing sand and gold could be a mixture of the two substances, where the gold particles are mixed with the sand particles. If water and iodine are added to this mixture, the water could dissolve the iodine to form a solution, leaving the sand and gold particles unchanged.
