There are a few different ways to separate a mixture of sulfur and charcoal. One way is to use the difference in their densities. Sulfur is denser than charcoal, so it will sink to the bottom of a container if the mixture is stirred or shaken. The charcoal will float on top, and it can be skimmed off.

Another way to separate sulfur and charcoal is to use their different chemical properties. Sulfur is soluble in carbon disulfide, while charcoal is not. So, if the mixture is added to carbon disulfide, the sulfur will dissolve and the charcoal will not. The charcoal can then be filtered out of the solution.

Finally, sulfur and charcoal can also be separated by sublimation. Sulfur sublimes at a lower temperature than charcoal, so if the mixture is heated, the sulfur will turn into a gas and the charcoal will remain solid. The sulfur gas can then be condensed and collected.
