24/04/2017 Tantalum comes from the processing and refining of tantalite. Tantalite is the common name for any mineral ore containing tantalum. Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum. The ore is then concentrated at or near the mine
The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures. This causes the tantalum and niobium values to dissolve as complex fluorides, and numerous impurities that were present also dissolve ...
Tantalum is produced by the processing and refining of its ore tantalite. 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 is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum ...

Approximately 71% of the global tantalum supply in 2008 was newly mined, 20% was from recycling, and the remainder was from tin slag and inventory. Tantalum minerals are mined in Colombia, Australia, Brazil, China, Ethiopia, and Mozambique. Tantalum is also produced in Thailand and Malaysia as a by-product of tin mining and smelting. Potential future mines, in descending order of magnitude ...
When he was approached by a mining company in 2016, Circulor CEO and co-founder Doug Johnson-Poensgen had never heard of tantalum himself. But he soon learned everyone from miners in Africa to electric car makers in California has a stake in the mineral. For example, consumers don’t want their purchases to support slave labor. Developing countries don’t want their exports tainted and ...

The tantalum-rich ore or ferroalloy is then crushed, ground, and decomposed in hydrofluoric acid. This is followed by a liquid-liquid extraction process, in which the two metals are dissolved in a slightly acidic aqueous feed solution into which an organic solvent, usually methyl isobutyl ketone, is mixed. The tantalum is extracted as a fluoride in the organic solution, while niobium remains ...
