Tantalite: The mineral columbite

The Mineral tantalite. Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. 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

Economic Geology of Niobium and Tantalum

Tantalum ore has characteristically grades of about 0.03% Ta 2 O 5, generally as a co-product of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hard-rock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.

Coltan ore, a sample of the element Tantalum in the

Coltan is a major ore for tantalum, used in capacitors found in nearly all digital electronics, including cell phones (and computers and talking dolls and defibrillators and pretty much everything else invented since 1980). The problem with coltan is that some of it comes from a region in the Congo that is one of last habitats for gorillas.

Coltan

Coltan is a dull black metallic ore, from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite, and the tantalum-dominant mineral is tantalite. Tantalum from coltan is used to manufacture tantalum capacitors, tantalum capacitors are used for portable telephones, personal computers, automotive electronics and cameras. Coltan mining has

Mineral profile Niobium

The columbite-tantalite mineral group (Figure 1) is the most common group of tantalum- and niobium-bearing minerals. Wodginite is also an important source of tantalum. The pyrochlore group (Figure 2) is of great economic importance, particularly for niobium. This group has a

BGR

Regional Production: In the Great Lakes Region, tantalum is most commonly found in association with niobium in minerals of the columbite-tantalite group [(Fe,Mn)(Nb,Ta)2O6]; "coltan" has been established as a trade name for such tantalum-bearing ore concentrates in Africa. Coltan mining is common in Rwanda, the DRC and, to a lesser degree, in Burundi.

Facts about Tantalum: Applications Uses

Jun 18, 2018Tantalum (Ta) is an unsung hero in modern metallurgy. First discovered by the Swedish chemist Anders Ekeberg in 1802, this versatile metal has become essential to numerous industries over the years. Raw tantalum rarely occurs in nature. Instead, it is typically found in the ore columbite-tantalite (usually referred to as coltan).
