¹World totals and estimated data are rounded to no more than three significant digits; may not add to totals shown.
²Table includes data available through May 25, 2007.
³Tungsten concentrates are thought to be produced in Nigeria, Peru, and Turkey and may be produced from tin-tungsten ores in�
Kyrgyzstan, but information is inadequate to make reliable estimates of production.
⁴Reported figure.
⁵Includes tungsten content of tin-tungsten concentrate produced by state-owned mining enterprises under the Ministry of Mines.
⁶Tungsten content of concentrates shipped.
⁷Based upon data published in the Yearbook of Nonferrous Metals Industry of China.
