Abstrakt: The article discusses the results of experiments on the extraction of bitumoids from carbonaceous shales from the Patom Highland in Eastern Siberia, Russia. Study authors analyzed whole-rock samples of shales and ores for carbon. They found that aluminum is present in the filtrate solutions and the filter cake. Results showed that bitumoids as relics of primary disseminated carbonaceous matter (DCM) of the metamorphosed shales have gold in its metallic state and in chemically bound modes.
