Sublimation is the process to separate iodine from a mixture of iodine and common salt.
Sublimation is a physical process in which a substance changes from a solid directly to a gas without passing through the liquid phase.
Iodine on being slightly heated changes directly from solid to gas. These vapors condense into a solid crystalline structure when then they come in contact with a cold surface. Sodium chloride on the other hand has a very high temperature of changing state. It melts at over 800 degrees.
To separate sodium chloride and iodine the best way is to slightly heat the mixture. The dark purple vapors of iodine can be collected and cooled to give solid iodine. During this process, sodium chloride is not affected.
