The Uses of Tantalum & Tantalum Alloys. 1. The Uses of Tantalum in the Field of Capacitors. 50%-70% of the world's tantalum is used to make tantalum capacitors in the form of capacitor-grade tantalum powder and tantalum wire. Since the surface of tantalum can form a dense and stable oxide film with high dielectric strength, it is easy to ...

Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of high-strength steel alloys used in pipelines ...

Tantalite contains some niobium, with the mineral being referred to as niobite or columbite when the niobium content is greater than that of tantalum. Indeed, until the discovery of the world's pyrochlore deposits in the 1950s, niobium was a by-product of tantalum mining, with increasing demand ensuring that it was highly valued and highly ...

THE MINERAL COLUMBITE. Chemical Formula: (Fe, Mn, Mg) (Nb, Ta) 2 O 6, Iron Manganese Magnesium Niobium Tantalum Oxide. Uses: An ore of niobium and tantalum and as mineral specimens. Columbite is the most widespread niobium mineral and makes for an important ore of the industrially useful metal. Niobium, Nb, is used in alloys for improved strength.

Tantalum is sometimes, but only rarely, found uncombined in nature. It occurs mainly in the mineral columbite-tantalite, which also contains other metals including niobium. It is mined in many places including Australia, Canada and Brazil. There are several complicated steps involved in separating the tantalum from the niobium.

Cassiterite is the best-known tin mineral. It has been used as the chief ore of tin from early history throughout the ages, and remains so even today. Some of the economical Cassiterite deposits exist in placer stream deposits where this very heavy mineral collects as rounded waterworn pebbles. The name Cassiterite is derived from the Greek "kassiteros", meaning tin.

Tantalum was mined for many years until its closure in 2012 by previous owner GAM. Tantalum and lithium are both located within a series of mostly flat to shallow-dipping pegmatites. Mineral Resources purchased the Wodgina deposit, tenements and associated infrastructure from GAM in late 2016, with GAM retaining the tantalum rights.

Tantalite forms a solid solution series with Columbite known as the Columbite-Tantalite series. 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.

Metallic mineral resources such as gold, copper, iron, and aluminum, and non-metallic mineral resources like gravel, building stone, sand, gypsum, and salt are invaluable to our everyday life. Today's technology relies heavily on extremely rare metals such as tantalum, beryllium, and lithium, all of which are extracted from rocks and minerals.

Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low grade and contain only 0.01 to 1 percent tantalum pentoxide, which is equivalent to 0.1 to 10 kilograms per metric ton. As a result, to produce concentrates of tantalum, tantalite ore must be separated from other minerals in the ore.
