Tantalum and niobium processing can be difficult because the minerals are brittle, heavy and typically highly intergrown with sulfide and other oxide minerals. SGS has contributed to many tantalum projects over the years and can bring an integrated suite of services to tantalum and niobium exploration or development projects.

Tantalum and niobium processing can be difficult because the minerals are brittle, heavy and typically highly intergrown with sulfide and other oxide minerals. SGS has contributed to many tantalum projects over the years and can bring an integrated suite of services to tantalum and niobium exploration or development projects.
Tantalum is mostly found in specialized or highly fractionated granitic rocks and their related pegmatites. It also occurs in placer deposits along with tin minerals and historically processed tin slags have been an important source of the metal. Avalon has two potential sources of tantalum in its portfolio.

Other tantalum bearing minerals include ferrotantalite, manganotantalite and microlite. Tantalum and niobium are almost always found together, and are recovered from pegmatite veins in granite intrusions or from placer deposits. Tantalum is mined in Australia, Brazil, Canada and Central Africa.
Tantalum minerals with over 70 different chemical compositions have been identified. Those of greatest economic importance are tantalite, microlite,and wodginite however, it is common practice to name any tantalum containing mineral concentrate as tantalite primarily because it will be processed for the tantalum values and is sold on that basis.The minerals are concentrated by physical

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.

Tantalum usually occurs together with Niobium in the same type of mineral deposits and in minerals of similar characteristics. These metals are often found in solid solutions, as is the case with columbite tantalite, represented by the formula Fe,Mg,Mn Nb,Ta 2O6, or minerals from the pyrochlore group. Mineral deposits from which Tantalum is
Pegmatites form the host for the majority of Australian tantalum deposits, commonly occurring with tin cassiterite and or lithium mineralisation, e.g., the Western Australian deposits of Greenbushes and Wodgina. Tantalum by product grades in these deposits range from 100 to 400 ppm. Tantalum and niobium are also found in other deposit types

Dec 15, 2013 0183 32 Because of its high resistance to corrosion by most acids, tantalum is used increasingly by petroleum and chemical plants. Global demand for tantalum has increased since the mid 1990s, due to the use of tantalum capacitors in small portable electronic components such as laptop computers, video cameras, game consoles and mobile phones.
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 niobium.
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
