The DFS considers the construction of two 825ktpa processing plants, for a total processing capacity of 1,650ktpa, with the construction of the second plant to potentially be funded from projected cash-flows derived from graphite sales from the first plant. The plants are based on identical designs. Crushing Crushing will occur in two stages.

As the high value and the scarcity of large-flake graphite ore resources, it is in the best interest to maximize the amount of large flakes and minimize any processing that will reduce flake sizes. In the study, the mineralogy of an African graphite ore was estimated using X-ray diffraction (XRD), X-ray fluorescence (XRF), and optical microscope analyses.
