  • TANTALITE (Iron Manganese Tantalum Niobium Oxide)

    Tantalite is the more tantalum rich end member and columbite is the more niobium rich end member. Niobium had been called columbium hence the name columbite. Tantalite's greatest difference from columbite is its much greater specific gravity, 8.0+ compared to columbite's 5.2. Other properties that vary slightly are color, transparency and streak. Both minerals can be found more or less

    Despite its importance in the world today, tantalum mining takes place in very few countries. Only four countries produced tantalum in 2016, and most was mined in the Democratic Republic of Congo (DRC) Africa. Rwanda took the top spot for tantalum mining in 2015, but in 2016 the DRC took the lead again, producing about 40 percent of the worlds tantalum.

    The mining boom is estimated to have boosted real per capita household disposable income by 13 per cent over the decade to 2013. The boom contributed to a large appreciation of the Australian dollar that has weighed on other industries exposed to trade, such as manufacturing and agriculture. Model estimates suggest that manufacturing output in 2013 was about 5 per cent below what it would have

    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 quot;columbite tantalitequot; in many mineral guides. However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2). Iron rich tantalite
