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.
