The meeting discussed the molybdenum and tungsten quantum chemistry, metal chemistry, as well as tungsten concentrate wet metallurgy processing technology and other issues. Siberian Branch of the Soviet Academy of Sciences Buryat Institute of Natural Science reported on the comprehensive utilization of resources Buryat mineral resources. The Institute has developed a joint process for the treatment of tungsten-depleted ores of the Buryat Autonomous Region, including the re-election of coarse grained tungsten
