New prospective sources of valuable minerals, including substantial reserves of crystalline graphite, gold, platinum, rare earth elements, and diamondlike carbon, have been revealed by the authors in high-carbon rocks in the south of Russia’s Far East. A scheme has been developed for the hydrometallurgical recovery of strategic metals and extra-pure (99.98%) crystalline graphite, used as a base material for conducting plasma-chemical investigations, from graphite ore. As a result of the experiment, nanodiamonds have been recovered, which were presumably inherited from the natural graphite-containing rocks.
