Metal contents of brown coals of Middle-­Amur coalfield

Presented the results of researches of metals content of rare-­valuable metals and estimations of resources of these metals in the brown coal deposits of Middle Priamurye (Ushumunsky, Liansky, Hurmulinsky, Muhensky). In coals of the studied deposits the total increases of prognostic resources (P₂ + P₃) of metals are more than Sc 10, V 60, Ga 14, Rb₂O 54, Cs₂O 9, TR₂O₃ 195, WO₃ 20 th. tons, etc. Brown coal deposits with rare metals form, valuable metals form a nonconventional mineral base of rare metals.
Keywords: rare metals, coal, coal deposits with rare metals, concentrations, prognostic resources, increase of resources, complex raw materials, Middle­-Amur Coalfield.
