Three coal basins in East Siberia, the Russia Lena, Kansk-Achinsk and South-Yakutsk basins, are huge coal basins which contain various sorts of both brown and high quality subbituminous and bituminous coals with low ash and sulfur content. The coals have great industrial significance for the production of energy, coke and chemicals. However, these coals are less characterized in terms of the content and distribution of trace metals, some of which are of industrial significance, other metals are toxic and radioactive. The data on the distribution of trace metals in these three coal basins, their geochemical occurrence and the behavior in chemical treatment and burning are presented in the paper. Separate coals were found to contain a large amount of valuable metals such as Ge (up to 1,400 g/ton of ash), V (up to 1,400 g/t), Sc (up to 220 g/t), Nb (up to 280 g/t), Cr (up to 1,300 g/t), Co (up to 320 g/t), Ni (580 g/t) and thus could be an industrial source of metal production. The methods for the extraction of Ge, Sc, Y, Nb and other metals prior or after combustion are described. The aspects of coal characterization in terms of toxic and radioactive impact on the environment are discussed.
