前段时期由于国际市场金属钨过剩 ,迫使一些西方企业退出市场 ,而前苏联的解体又导致该地区钨矿开采与冶炼产量的急剧下跌 ,中国成了钨矿开采与冶炼的主要国家 ,1 999年中国开采的钨矿约占世界总产量的 85%。从 2 0世纪 80年代末世界金属钨产量急剧下降以来 ,世界钨消费量已多 In the previous period, due to excess tungsten metal in the international market, some western enterprises were forced to withdraw from the market and the collapse of the former Soviet Union led to the drastic drop in tungsten mining and smelting output in the region.
