Abstract
A mining method (10) by which graphitic ore is produced in a form that constitutes an appropriate feedstock for an electrolytic process (20) for the production of graphitic materials through exfoliation. The graphitic ore feedstock may be utilised directly as an electrode in the electrolytic process (20). Also disclosed is a graphitic feedstock for an electrolytic process for the production of graphitic material through exfoliation of that feedstock, wherein the feedstock is less than about 99% graphite (w/w) and of a sufficiently cohesive and conductive nature as to allow electrochemical exfoliation therethroughout without fracturing that might result in collapse of a significant portion of the feedstock or that may result in a loss of conductivity throughout a significant portion of the feedstock.
