A process and system for the reduction (by milling), separation and recovery of carbon contained in char, coke and other residues resulting from distillation or destructive distillation of carbon-containing materials. The process or system includes ball or rod mill means for pulverizing incoming carbonaceous materials such as char, routing the output of the mill to a classifier so as to provide for a large particle return, conveying the output of the classifier to a flotation system wherein appropriate reagents are added to effect froth recovery, and finally, thickening the result of the material and otherwise processing it so that a carbon cake may be derived, dried, and deposited for carbon storage. Resultant carbon is thus produced in essentially a pure form, rivaling that derived through current mining processes.
