Filtration: This method is based on the difference in the physical properties of sulfur and sodium chloride. Sulfur is insoluble in water while sodium chloride is soluble in water. Therefore, a mixture of sulfur and sodium chloride can be separated by dissolving the sodium chloride in water and then filtering the mixture. The sulfur will remain on the filter paper while the sodium chloride solution will pass through.

Sublimation: This method is based on the difference in the sublimation points of sulfur and sodium chloride. Sulfur sublimes at a lower temperature (444.6 K) than sodium chloride (1073 K). Therefore, a mixture of sulfur and sodium chloride can be separated by heating the mixture to a temperature between 444.6 K and 1073 K. The sulfur will sublime and can be collected on a cool surface while the sodium chloride will remain in the solid state.

Extraction: This method is based on the difference in the solubility of sulfur and sodium chloride in different solvents. Sulfur is soluble in carbon disulfide while sodium chloride is not. Therefore, a mixture of sulfur and sodium chloride can be separated by adding carbon disulfide to the mixture and then shaking it. The sulfur will dissolve in the carbon disulfide while the sodium chloride will remain undissolved. The carbon disulfide solution containing the sulfur can then be separated from the sodium chloride by decantation or filtration.
