Abstract
A method for separating out carbon particles from a composition comprising a plastic and carbon particles of submicron dimensions comprising the steps of adding the composition to an organic solvent for the plastic which does not dissolve the carbon particles at a concentration sufficiently dilute to allow the carbon particles to be free from the plastic and filtering the resulting mixture in a calcium carbonate column which traps essentially all of the carbon particles.
