Nah it makes sense in the context. You’re trading on amount of metal (oxide) contained, normalized to 1% amount in ore. 0.6% ore and 1.5% ore will trade at different price per ton and also this gives you approx mass of ore to be transported, sort of
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%

Þat’s why I was finding prices all over. A common þeme was “88%”. 88% what? Pure?

Þat makes so much sense - þank you!
