Tantalum is a chemical element; it has symbol Ta and atomic number 73. It is named after Tantalus, a figure in Greek mythology. [11] Tantalum is a very hard, ductile, lustrous, blue-gray transition metal that is highly corrosion-resistant.
There are 2 parts per million of tantalum in the Earth's crust, making it the 51st most abundant element there. Soil contains on average 1 to 2 parts per billion of tantalum, and seawater contains 2 parts per trillion of tantalum. A typical human contains 2.9 parts per billion of tantalum. Tantalum is found in the minerals tantalite and ...
Kenticha was mined for tantalum from 1990-2017. [5] Peak production from the mine was 90-95 tons of tantalum concentrate per year, valued at $20 million dollars/year. [3] Another sources states that before 2012, the mine produced 275 tons of tantalum/year, which was nearly 14% of global supply. [6]
The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) resistant metal.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.
The United States does not produce tantalum due to the poor quality of its reserves. [20] Australian mining company Sons of Gwalia once produced half the world's tantalum but went into administration in 2004. Talison Minerals paid $205 million to buy the Wodgina and Greenbushes tantalum business of Sons of Gwalia but temporarily closed Wodgina ...
In November 2019, the Government banned mining cooperatives and companies from selling gold to private buyers. The Central Bank was established as the sole buyer of gold. [11] Between 2015 and 2019 estimated annual gold production fluctuated between 396 kilograms (873 lb) and 953 kilograms (2,101 lb). [12]
