Concentrates International Tungsten Industry Concentrates. Marketable ore concentrates of scheelite and wolframite (hbnerite, ferberite) contain typically 65 70 % WO 3.Off-grade concentrates having lower WO 3 concentrations are seldom on the market and if so, only for a lower price. World demand for processed tungsten will rise 4.2 percent yearly to 146,400 metric tons in 2019. The Asia/Pacific region, led by China, will continue to dominate supply and consumption, while India will be the fastest growing market. Tungsten alloys will pace gains by product, while cemented carbides remain the largest segment.This study analyzes the 119,100 metric ton world tungsten industry
