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.

Tantalum and niobium
Summary. Niobium and tantalum do not occur naturally as free metals. The charge to ionic ratio of tantalum and niobium results in strong bonds being formed with oxygen; in fact, most niobium–tantalum minerals are oxides, rather than silicates, sulfides or phosphates. Three types of niobium and tantalum deposits are: carbonatite-hosted ...
