Tantalum Responsible Minerals Initiative

Tantalum is extensively used in products that require high reliability in extreme environments. The metal is commonly found in capacitors and super alloys that are applied in many electronics, automotive and aerospace products. More than half of the world’s tantalum is mined in Africa, including artisanal

Mineral Resource of the Month: Tantalum EARTH Magazine

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.

On the trail of tantalum: tracking a conflict mineral

20-04-2016· Although 50%-60% of the world’s tantalum ends up in electronics, many other industries use conflict metals in their products, including for apparel, medical devices and automotive production. "It was really interesting that the industry came together to conflict-free sourcing initiative, to really help create the tools and mechanisms necessary."

Tantalite Wikipedia

The mineral group tantalite [(Fe, Mn)Ta2O6] 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). Iron-rich tantalite is the mineral tantalite-(Fe) or ferrotantalite and manganese-rich is tantalite-(Mn) or manganotantalite.

Tantalite: The mineral columbite-tantalite information

Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum. The name Tantalite has been discredited by the IMA,with the more specific designations of Tantalite-(Fe) (also known as Ferrotantalite ), and Tantalite-(Mn) (also known as Manganotantalite ) being used for this mineral's IMA-accepted nomenclature.
