The African Tantalite Mining Industry
Tantalite is a mineral group and the main source of tantalum, a chemical element which is hard, rare, and considered to be an important commodity, especially in the electrical and computer industries. Because it has a melting point of more than 3,000 degrees Celsius, this brown-to-black-coloured mineral can sustain high temperatures and is ...

Tantalite - Wikipedia
The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum.It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides. However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2).
