According to sources, Minmetals last weekend asking the next miner inventory, consulted the next single, but in the meantime and not out of the acquisition plan, the latter will continue purchasing and storage is not clear. According to research, at present more than 60 degrees wool wolframite ore price 1.78 yuan / kWh nearby and procurement needs less; business confidence, traders are afraid to purchase tungsten, fearing heart harder shots. And due to lack of demand and financial pressure, cash transactions of small quantities of tungsten, the price even lower than the gross price is also mine.
