Tantalum
3 Tantalum. Tantalum is a relatively rare element, and commercial quantities are found in Australia, Brazil, Canada, and Africa. Tantalum is also present in tin-bearing ores and remains in the slag from tin refinement. Tin processing is, in fact, the primary source of commercial tantalum, since the processing of other sources are much more costly.

Mineral Resource of the Month: Tantalum
Tantalum — a rare, blue-gray, very hard transition metal — was discovered in 1801 or 1802. However, extensive use of the metal did not begin until 1940, when it became an important material for capacitors used in electronics. Tantalum is almost always found with niobium. Although it is a metal, tantalum is not found in metallic form in nature.
