    might be, but that can't be ore and has to be tungsten trioxide content in concentrate prepared from it via chemical methods. two common tungsten ores have 60% and 63% tungsten metal content when pure, tungsten trioxide is 79% metal, and there's also 80% of tungsten trioxide in these ores

    common tungsten use is in carbides and these contain 12% of cobalt as binder, hence 88%
