Tantalite forms a solid solution series with Columbite known as the Columbite-Tantalite series. Tantalite is the tantalum-rich member and Columbite is the niobium-rich member. Tantalite is named after its tantalum content and together with Columbite are the most important minerals containing the rare element tantalum.
Raw tantalum rarely occurs in nature. Instead it is typically found in the ore columbite-tantalite usually referred to as coltan. Once extracted pure tantalum is a hard blue-gray lustrous metal.
Since its discovery tantalum has been used in a number of applications. In the 21st century it has become a crucial element in the electronics industry with over 75 of electronics containing tantalum in some form. In particular engineers have been able to take advantage of some of tantalums properties to make capacitors and other components smaller and more efficient.
Tantalite is the mineral ore containing tantalum. Most tantalum mines are open pit whereas some are underground. The mining process involves blasting crushing and transporting the tantalite ore to start the process of separating tantalum. The ore is then concentrated at or near the mine site to increase the weight of tantalum oxide and niobium after which the material is concentrated through wet gravity
TantalumV and niobiumV can be extracted into the TBP phase either at high or low HF acidity. During extraction HNbF 6 .3TBP and HTaF 6 .3TBP complexes are generally produced. Tantalum and niobium are selectively stripped out from these loaded organic phases into the aqueous phase by ammonia.
Nov 01 2012nbsp018332Tantalite ore was digested using molten ammonium bifluoride. Niobium and tantalum were extracted using octanol as extractant. Addition of H 2 SO 4 improves the separation of niobium and tantalum. Extraction with 2-octanol is almost similar to extraction with 1-octanol. Two and three stages were sufficient for the extraction of Ta and Nb respectively.
In terms of mechanical properties tantalum is highly ductile making it suitable for processes such as bending stamping and pressing. When combined with other metals it can produce alloys with enhanced strength and higher melting points.

The probable ore reserves at Bald Hill mine are estimated at 11.3Mt of lithium ore and 2Mt of tantalum ore. The mine is estimated to contain 114100t of Li 2 O and 1.4Mlb of Ta 2 O 5. Mining at Bald Hill mine. The Bald Hill lithium and tantalum mine is being developed in two phases with the first phase focused on starting lithium production.
Tantalum concentrate spot prices rose sharply in the first half of 2018 passing the US100lb Ta 2 O 5 level in mid-year. They then started to fall and were at about US80lb by the end of November. Prices have continued to fall through the new year and are currently believed to be considerably lower.
Apr 29 2020nbsp018332Tantalum is a rare transition metal that is highly resistant to corrosion and has important applications in electronic equipment. In 2019 the price of tantalum was approximately 162 U.S. dollars .
