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).

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 ...
Francis Gatare, the chief executive of Rwanda Mines, Petroleum & Gas Board (RMB), pointed out that the mining sector was continuing to grow and that Rwanda was diversifying the sector. "Mining continues to grow in importance and size. For long, the mining sector was dominated by 3Ts (tin, tantalum and tungsten)," he noted.
Canadian tantalum reserves are est imated to contain more than 3,000 t of contained tantalum. U.S. tantalum resources are of low grade, and none were considered economically minable in 1998. PRODUCTION AND PRODUCTION PROCESSES The United States, which has no tantalum mining industry, must import all its tantalum source materials for processing.
In 2014 Rwanda was shown to have produced 50% of all global tantalum concentrates (and 25% of global tantalum metal), up from just 12% in 2000. Mining contributes to about 1.5% of Rwanda's $7.8bn GDP, and the country has recently signed a five-year mining contract worth $39m with a unit of Oman's Mawarid Mining to extract tantalum, tin and ...

Prior to the shift, Australia & Brazil were the major tantalum mining countries. Beginning in 2007, the DRC, Rwanda, and other African countries became the major sources of tantalum production. The production shift from Australia was a result of high extraction costs and an unfavorable exchange rate, which meant that mining tantalum ore in ...
Tantalum mineral concentrates may contain from two to more than five different tantalum-bearing minerals from the same mining area.The sale of tantalum mineral concentrates is based on a certified analysis for the tantalum oxide (Ta 2 O 5) they contain,with a typical range from 20% to 60% depending on the mine source.

Refining - Tantalum. Tantalum. Pure tantalum is not found naturally. Tantalum i. . s obtained commercially by first creating tantalum oxide (TaO 5). The tin industry also produces tantalum as a by product from smelting cassiterite ore concentrates for processing. The biggest tantalum mine is the Mibra operation in Nazareno, Brazil.
Tantalum ore is composed of both tantalum and non-tantalum containing minerals, and the Ta 2 O 5-equivalent content is typically 0.02–0.04 percent. Low-grade tantalum ore is physically concentrated (beneficiation) to a concentrate of 20–40 percent Ta 2 O 5 -equivalent at the mining site before sale to smelters ( Linnen et al., 2014 ).
