A method of processing particulate carbon comprises combining pyrolysis carbon with water to form a mixture to form an initial slurry having 1-35 wt% solids and milling the pyrolysis carbon to form a milled slurry comprising wet milled reclaimed carbon and water; wherein a volume weighted particle size distribution of the wet milled reclaimed carbon measured via scanning electron microscopy has one or more of D50 no greater than 2700 nm and no more than 15% of particles having a particle diameter greater than 5 microns.
