production, trade and apparent consumption of tungsten in the U.S.S.R. from the inception of tungsten mining in the early 1900's through 1986. By far the greatest emphasis is placed on reserves, mining, beneficiation and consumption of Soviet tungsten deposits and ores therefrom, and on trade in ores and concentrates.
Electrical Properties323 Кб. MINING & BENEFICIATION Tungsten is usually mined underground. Scheelite and/or wolframite is frequently located in rather narrow veins which areturnings, grindings and powder scrap are oxidized and chemically processed to APT in a way similar to that used for the processing of tungsten ores .
