tantalum ore

Tantalum Processing | TIC

Tantalum metal powder, including the precursor to capacitor grade powder, is generally produced by the sodium reduction of the potassium tantalum fluoride in a molten salt system at high temperature. The metal can also be produced by the carbon or aluminium reduction of the oxide or the hydrogen or alkaline earth reduction of tantalum chloride.

Sample Preparation Guides

Niobium and Tantalum metals resemble Platinum in appearance when polished and they are somewhat darker and bluer when unpolished. The metals are attacked by HCl, HNO 3 or Aqua Regia, hot or cold, dilute or concentrated. There is no reaction with hot dilute H 2 SO 4, but boiling, concentrated H 2 SO 4 slowly dissolves them.

Tantalum | Article about tantalum by The Free Dictionary

Tantalum is obtained chiefly from the mineral tantalite, although it also occurs in euxenite, samarskite, and some other rare minerals. 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.
