From the perspective of foreign supply, tungsten concentrate production remained generally stable. As the tungsten market continues to decline for many years, the number of tungsten mines that have stopped production, reduced production, and stopped construction in foreign countries is still high, resulting in a decline in global tungsten concentrate output. At current prices, some foreign tungsten mines are still difficult to start. In the future, the foreign market supply will remain stable. The supply and demand contradictions in the tungsten market will continue to improve. Russia is rich in tungsten resources and is the second largest tungsten resource country in the world, accounting for about 14% of the global tungsten resources. Affected by multiple factors, Russia’s tungsten concentrate production fell from 20,000 tons (WO3) in 1990 to 3,300 tons (WO3) in 2016, yields stabilized; CantungMine tungsten mines in Canada are subject to environmental, transportation, and cost issues. It was difficult to resume production in December 2015 when production was suspended. The tungsten mine of Mactung Mine has not yet been developed. The tungsten mines in Spain, Portugal, Bolivia, Austria and South Korea are under construction or are out of production. And remained stable; after the tungsten mine in Hermdon, UK was put into operation in 2015, due to the beneficiation process, cost, and funds, only half of the production capacity can be achieved at present; the output of the tungsten mine in NiuPhong, Vietnam remained stable. Production increase plans; production of tungsten concentrates such as Rwanda, Australia, and Brazil is low or has stopped production. The tungsten and strategic reserves of the United States and Russia are at historically low levels, and Russia’s own tungsten supply cannot meet its normal domestic demand. At the same time, due to the devaluation of the ruble, labor costs are relatively low, and tungsten products have a price competitive advantage, but due to the small output, the impact on the market is limited.
