[68] [67] [69] Because of its ductility, tantalum can be drawn into fine wires or filaments, which are used for evaporating metals such as aluminium. Tantalum is inert against most acids except hydrofluoric acid and hot sulfuric acid, and hot alkaline solutions also cause tantalum to corrode. This property makes it a useful metal for chemical ...
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 ...

In August 2010, Noventa's first shipment (since reopening) of 8 tonnes of tantalum to an Asian client left the country from Quelimane. [8] Early 2012, Cyclone Funso caused some damage to the mine's buildings, along with minor floodings. The cyclone also brought a plague of non-endemic, poisonous rove beetles that affected 30% of the mine's ...
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]
