The World Production from Mines

The W content of the ores varies from mine to mine in the range of 0.1 to 2%. The production of ores and concentrates varies greatly according to demand and price, and some mines have shut down. The price level is the reason for closing the Canadian mines although the country has about 15% of the total world tungsten reserves. 

In the year 2000 the total production in all mines of the world was not far from 40 thousand tonnes (contained tungsten). Of this China accounted for about 80% (see Table 26.1).
