Tungsten ore resources

First, the resource situation
     Tungsten eletrode ore resources is the advantage of our mineral resources. Have been discovered and proven reserves of 252 mines, total proved reserves (WO3, the same below) 6,375,000 t, where A + B + C class reserves of 2.32 million t, accounting for 36.4%. As of the end of 1996, tungsten ore reserves as 5,290,800 t, where A + B + C class reserves of 2,281,100 t, accounting for 43.1%.
     Chinese tungsten wire ore is rich in resources, is known the world, and its reserves in the world ranking, with China table A + B + C class reserves of the world reserve base in the world compared to the first one. No. 2 Canada (reserve base of 493 000 t), No. 3 Russia (reserve base of 355 000 t). Chinese tungsten ore reserves in the world not only the first, but also production and export volume ranking first in the world a long time, they have been acclaimed as "the world three first."

Second, the reserves distribution
