Recrystallization and Sublimation are two commonly encountered methods of Purification. Several of these are done in the laboratory to obtain a pure sample of a particular organic compound.
Recrystallization literally means to crystallize again.
Sublimation involves heating the compound at low pressure from one apparatus and and condensing it in another. This is quite the same as distillation but of solid state.
Many methods exist: precipitation and filtration, distillation, dissolution and recrystallization, sublimation, sedimentation etc.
The principal steps are: grinding, dissolution in water, filtering, refining by repeated crystallization/recrystallization processes.
Recrystallization is used to purify solid organic compounds by dissolving the compound in a hot solvent and then allowing it to slowly cool. As the solution cools, the compound will crystallize out, leaving impurities behind in the solution. By filtering and drying the crystals, a purer form of the compound can be obtained. Multiple recrystallization steps can be performed to increase the purity of the compound.
A solid can be purified through techniques such as recrystallization, distillation, sublimation, or chromatography. These methods involve separating impurities from the desired compound based on differences in properties like solubility, boiling point, or affinity for a stationary phase.
Activated carbon is also known as decolorizing carbon. It is used to remove the colored impurities from the sample. Activated carbon provides a high surface area to absorb colored impurities. http://designer-drugs.com/pte/12.162.180.114/dcd/chemistry/equipment/recrystallization.html

Sodium chloride is not purified by sublimation.
Recrystallization is used to purify solids by dissolving them in a solvent and then allowing them to reform into crystals. This process helps remove impurities and improve the overall quality of the solid.
the magma or lava heats the rock it is in contact with, causing recrystallization
I think the answer is sublimation

The crystallization/recrystallization of sodium chloride from water solutions is frequently used.
It is called sublimation.
