How is tantalum mined
WebThe sale of tantalum was used to fund wars and conflicts in this region. Another point is that mining tantalum has ethical and sustainability issues, in terms of environmental impact. However, approximately 99% of tantalum comes from other regions, like Australia, where it’s mined more responsibly. WebTantalum metal powder, including the precursor to capacitor grade powder, is generally produced by the sodium reduction of the potassium tantalum fluoride in a molten salt system at high temperature. The metal can also be produced by the carbon or aluminium reduction of the oxide or the hydrogen or alkaline earth reduction of tantalum chloride.
