1World total and estimated data are rounded to no more than three significant digits; may not add to totals shown.
2Except for Congo (Kinshasa) and Rwanda, excludes production of niobium and tantalum contained in tin ores. Includes data available through August 25, 2015.
3Gross weight is weight of concentrate before metal is extracted.
4Content is weight of metal produced. Nb2O5 is 69.904% niobium; Ta2O5 is 81.897% tantalum.
5In addition to the countries listed, Russia was thought to have produced niobium and tantalum mineral concentrates, but available information is inadequate to
-make reliable estimates of output levels.
6Tantalum production reported in Ta2O5 converted to tantalum content. Gross weight is concentrate assumed to be one-third Ta2O5.
7Reported figure.
8Niobium concentrate production reported in Nb2O5 content converted to niobium content. Gross weight is concentrate assumed to be one-third Nb2O5.
9Includes columbite and pyrochlore.
10Includes djalmaite and tantalite.

14From August 2008 to April 2009, 18 metric tons of columbite-tantalite were reportedly produced in Somalia. It is unclear if production continued after early April 2009.
