Abstract
Disclosed is a method for producing rough spherical graphite, whereby rough spherical graphite can be mass-produced at low cost with high efficiency. The method comprises: a) a step for pulverizing natural flake-shaped graphite; b) a step for mixing the pulverized natural graphite of step a) and a liquid pitch including a solvent and pitch; c) a step for removing the entirety or a portion of the solvent from the mixture of step b) for which mixing has been completed; d) a step for producing a rough spherical graphite by rough spheroidizing the mixture of step c) from which the solvent has been removed; e) a step for heat-treating the rough spheroidized graphite of step d); and f) a step for classifying the heat-treated rough spherical graphite of step e).
