Answer 1

Solvent extraction is the method is used to separate substance from one or more others by using solvent.In this process one of the component of a mixture dissolves in a particular solvent, and the other component which does not dissolve is separated by filtration.

The sulphur component dissolves in solvent and the undissolved carbon is separated by filtration. The dissolved sulphur can be separated from the solution by evaporation.
