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 nonreactive and nonirritating to body tissues.
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 semisingular mineral called coltan or "columbitetantalite" in many mineral guides.
What is tantalite/tantalum? Tantalite (or coltan) is a naturally occurring oxide; the main ore and source of oxides and metallic tantalum Tantalum is the refined elemental metal .
Sources of tantalum Tantalum occurs naturally in the mineral columbitetantalite. It's mainly found in in Australia, Brazil, Mozambique, Thailand, Portugal, Nigeria, Zaire and Canada.

Columbite: Columbite, hard, black (often iridescent), heavy oxide mineral of iron, manganese, and niobium, (Fe, Mn)Nb2O6. Tantalum atoms replace niobium atoms in the crystal structure to form the mineral tantalite, which is similar but much more dense. .
Tantalum is a sensible choice whenever high corrosion resistance is required. This platinumgray colored metal has a density of g/cm3 which is twice as dense as steel. We use our "unyielding" material, for example, to produce heat exchangers for the equipment construction sector, charge carriers for furnace construction, implants for ...
