PROCESS FOR THE RECOVERY AND PURIFICATION OF GRAPHITE FROM SPENT BATTERIES

Provided herein is a process for recovery of graphite from black mass, comprising the steps of: initially separating the graphite from other components of the black mass; pre-purifying the separated graphite by means of treatment with an aprotic dipolar solvent and/or heat treatment, and sorting by particle size, shape and/or density; and further purifying the pre-purified graphite.
