Coal deposits of the Far East Russia and resource potential of precious metals contained in them
The results of metal-bearing industrial research and evaluation of predicted resources of rare and other valuable metals in coal deposits of the Far East are given. Geochemical association of metals and peculiarities oftheir concentration in the coals are shown.The total increase in the predicted resources of Ge in the coals of the studied fields of Primorye is estimated at more than 2.7 thousand tons. The resource potential of valuable metals was also estimated according to the categories of predicted resources P3 and PИ, from the studied coal objects of the Khabarovsk and Kamchatka Territories, the Jewish Autonomous Region, the Magadan and Sakhalin Regions. For them, the total number of predicted resources of rare metals in the P2 category is: Sc - 11.98 thousand tons, Ga - 10.94 thousand tons, Ge - 7.18 thousand tons, Rb2O - 40 thousand tons, SrO - 137 thousand tons, Cs2O - 3.6 thousand tons, ZrO2 - 36.3 thousand tons, TR2O3 - 212.8 thousand tons. According to the category P3: Sc - 14.4 thousand tons, Ga - 16.4 thousand tons, Ge - 9.8 thousand tons, Rb2O - 46,3 thousand tons, SrO - 125,7 thousand tons, Cs2O - 9,16 thousand tons, ZrO2 - 135.6 thousand tons, TR2O3 - 266.18 thousand tons. The amount of platinum group metals is 15.1 tons in P2 category, and 24.4 tons in P3 category. A metallogenic map of coal deposits in the Far East of Russia is constructed. Rare-metal-coal fields in the eastern regions of Russia form an unconventional mineral and raw materials base for rare metals.
