The world's reserves of tungsten are 3,200,000 tonnes; they are mostly located in China (1,800,000 t), Canada (290,000 t), Russia (160,000 t), Vietnam (95,000 t) and Bolivia. As of 2017, China, Vietnam and Russia are the leading suppliers with 79,000, 7,200 and 3,100 tonnes, respectively. Canada had ceased production in late 2015 due the closure of its sole tungsten mine. Meanwhile, Vietnam had significantly increased its output in the 2010s, owing to the majo

Tungsten element extraction method surface mining technique

Tungsten is generally mined underground. Scheelite and/or wolframite are frequently positioned in rather narrow veins which are faintly disposed and often widen with the intensity. Open pit mines subsist but are exceptional. The ore is first compacted and milled to unshackle the tungsten mineral crystals.

Tungsten MiningBeneficiation International Tungsten

Tungsten mines are relatively small and rarely produce more than 2000t of ore per day. Mining methods for tungsten ore are not at all exceptional and usually are adapted to the geology of the ore deposit. Most tungsten ores contain less than 1.5% WO 3 and frequently only a few tenths of a percent. On the other hand, ore concentrates traded internationally require 65-75% WO 3.
