Processes for preparing or handling graphene sheets wherein low bulk density graphene sheets are compressed. The graphene sheets may be produced by a thermal treatment such as exfoliation of precursor or reduction or annealing of previously existing graphene sheets and conveyed in a closed system to a compression apparatus.
