钨 经过多年的不景气以后,1986年钨矿业经受了近年来最糟的处境。价格比1985年下降30％,跌到了14年来的最低水平。精矿消耗比1985年减少17％,许多大矿山关闭,还有许多大矿山大幅度削减了生产。 中国人继续让他们的精矿在西方市场以最低的价格出售,同时以比精矿稍高或不高的价格抛售中间产品(仲钨酸铵和钨铁),结果导致价格呆滞,随后又螺旋形下降。南美的生产厂及美国的GSA的低价销售进一步促使了价格下降。
Tungsten After 1986, the tungsten industry suffered the worst situation in recent years after many years of recession. The price dropped 30% from 1985, dropping to its lowest level in 14 years. Concentrate consumption dropped 17% from 1985, with many large mines closed and many large mines slashing production. The Chinese continue to sell their concentrates at the lowest prices in Western markets while selling intermediate products (ammonium paratungstate and ferroterr) at slightly higher prices than their concentrate, resulting in sluggish prices and subsequent spiral declines. Lower prices in South American manufacturing plants and in the United States of America’s GSA have further driven down prices.
