Abstract: The present disclosure describes a method of separating a carbon allotrope from a salt and a separation system for the same. The method may include adding a solid comprising the carbon allotrope and the salt to a solution comprising the salt, performing a first filtration on the solution at a first temperature to remove the carbon allotrope from the solution, adjusting the temperature of the solution to a second temperature to precipitate a first portion of the salt, performing a second filtration on the solution at the second temperature to remove the first portion of the salt from the solution, adjusting the temperature of the solution to the first temperature to dissolve a second portion of the salt in the solution, and recycling the solution.
