Sodium chloride can be separated from rock salt by first adding water to the mixture to dissolve the sodium chloride. The separation then takes place in two stages:

• evaporation followed by filtration
•  distillation followed by decanting
• filtration followed by evaporation
• filtration followed by decanting
