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.
Tantalite Ore Tantalum is an important component in many modern technologies, and is used in capacitors for everything from computers to mobile phones. Despite its importance in the world today, tantalum mining takes place in very few countries.
Australia and Brazil have been the leading producers of tantalum mineral concentrates, although recently Ethiopia and Mozambique have also been significant suppliers of tantalum. Artisanal mining of columbite-tantalite (also called coltan) is practiced in many countries, particularly Burundi, the Democratic Republic of the Congo (Congo ...
Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.
However, you can always buy shares in mining companies that extract the metal. But you will need to understand that news concerning this commodity is very seldom reported, and it will be very hard to keep track of prices. Purposes Used for Tantalum. Tantalum is used in many industries, and it is deemed a critical component in many items.

Tantalite is found at many of the localities for columbite and also at several other places. A part of the tantalum in tantalite is almost invariably replaced by the closely allied metal niobium, and when the amount of the latter exceeds the former, the mineral is known under the name of columbite.
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.
This tantalite ore separator machine, is ideally suited for arid areas, for it can save water resources, and reduce dressing costs, opening up a new way for magnetite mining. These series of tantalite ore separator machine can meet the needs of small, medium and large mining processing plant, welcome to negotiate business.
Another benefit to Morefield mine tantalum is its origin in the USA guarantees it is 'conflict-free' and the cost of guaranteeing the chain of ownership is minimal compared to African tantalite. Tantalum concentrate/ore is often referred to as 'Coltan'.
Australia has historically been the world's largest producer of tantalum (as tantalite concentrates), providing approximately half of the world's mine output through mining operations at Greenbushes 250 kilometres (km) south of Perth in Western Australia (WA) and …
The chief tantalum ores are tantalite, which also contains iron, manganese and niobium, and samarskite, which contains seven metals. Another ore which contains tantalum and niobium is pyrochlore. The main mining areas are Thailandia, Australia, Congo, Brazil, Portigal and Canada. The demand of tantalum is about 2300 tonnes a year.
The mining and processing complex is built around the work done by a well respected Geologist.15 claims.3 of the claims have a proven geological resource of 100 000t of tantalite ore. And the remaining 12 are claims with an estimated resource potential as high as 1 million tonnes.

In pegmatites, tantalite crystallizes in a later stage than columbite, associating with albite, lepidolite, beryl, and other minerals. Tantalite is resistant to weathering and concentrates in placers, which are the main source for its extraction. It is used as an ore of tantalum.
Tantalum is a chemical element with atomic number 73 and the symbol Ta. Tantalum is a rare, hard, blue-grey, lustrous transition metal and is highly corrosion resistant, existing naturally in the mineral tantalite, always together with the chemically similar niobium.
