Chemically, tantalite is similar to columbite, and the two minerals are often grouped together in mineral guides. However, the specific gravity of tantalite is significantly higher than that of columbite. Tantalite is challenging to process and is therefore not extensively mined despite the rising demand for it as it. Processing Tantalite . Tantalite appears in granites and other hard rock ...
· Tantalitecolumbite crystals were also noted between mica sheets and at junctions of intersecting books of mica. Finegrained garnet is also associated with the tantalitecolumbite. Individual tantalite crystals examined by electron microscope varied in composition from % to % Ta2O5 and from % to % Nb2O5.
There are many kinds of tantalum niobium minerals during which columbitetantalite is the most valuable. With development of military industry, the demand of metal tantalum has been increased while other industries' demand has been also escalated. The popular electric separation does not work for all mineral of tantalum and niobium, and only tantalite, tapiolite, columbitetantalite ...

Alluvial columbitetantalite series (not analysed) pebbles to 8 mm in a jar from the Greenbushes Tinfield. Old material, probably late 19th or early 20th century with original label. This sample ended in the UK and was purchased in 2008 from Cornwall mineral dealer Nick Carruth.
TanCo purchases, processes and exports tantalite, columbite and cassiterite minerals from all producing areas of Brazil. Loed in Rondônia and serving all of Brazil, TanCo is a leading Brazilian mineral trading company specialized in processing and exporting tantalite (tantalum), columbite (niobium) and cassiterite (tin) minerals. Led by an ...
In 2015 the tantalite processing plant was recommissioned under ownership of Alliance Mineral Assets Ltd (AMAL). In 2016, Tawana Resources NL acquired a 50% interest in the project with an aim to discover and produce lithium spodumene concentrate in joint venture with AMAL. processing of columbite tantalite ores and concentrates
· Tantalum is a valuable rare element used in electronics manufacturing while columbite is used in forming alloys that are useful in nuclear, aerospace and gas turbine engineering. Raremetal pegmatites containing economic concentrations of columbitetantalite ore minerals (coltan) are widespread in the PanAfrican (600±150Ma) basement of Nigeria.

Tantalum ore has characteristically grades of about % Ta 2 O 5, generally as a coproduct of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hardrock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.
