Almost all tungsten miners became bankrupt or were shut down. The main tungsten assets situated at the Northern Caucasia were almost destroyed by low prices and relatively high production costs. In 1997 the hugest tungsten miner in the world - Tyrnausky GOK finally stopped its operation. It produced up to 40 thousand tons of W-concentrate per year during the times of Soviet Union and was a main source of raw material for "Hydrometallurg" conversion plant in Nalchik which became almost bankrupt after the closure of Tyrnausky GOK.

几乎所有的钨矿山企业被迫破产或关闭，位于北高加索地区的主要钨军工企业由于钨产品售价低廉和制造成高走等原因几乎全部陷入绝境。1997年，世界最大的钨矿开采企业泰尔诺斯基公司最终停产，这家企业在苏共联盟执政期间每年生产约40000吨钨精矿，是位于纳契克地区的湿法冶炼工厂的主要原材料供应企业，在Tyrnausky GOK停产后，这家冶炼工厂几乎破产。
