The major sources of tantalum ore are Australia, Brazil, and Canada. Tantalum is almost always found in association with niobium; separation of the two metals is difficult. Major uses of tantalum include electrolytic capacitors, chemical equipment, and parts for vacuum furnaces, aircraft, and missiles. Tantalum was used in the filaments of electric light bulbs and electronic tubes but has been ...
Tungsten, or wolfram, is a chemical element with symbol W and atomic number 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, tung sten or "heavy stone". Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone.

A typical tantalum / tin / tungsten crushing circuit consists of a grizzly screen which is fed from a run of mine (ROM) pad consisting of several ore types and grades which are blended to produce a steady feed. The grizzly undersize is broken up in a primary jaw crusher, with the jaw crusher product being further broken up in a secondary cone crusher. The secondary crushed ore is then often ...
