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 Mining Process. The tantalum concentrate is transported to the processor for chemical processing. The concentrate is then treated with a mixture of hydrofluoric and sulphuric acids at high temperatures. This causes the tantalum and niobium to dissolve
Aug 23, 2019 Uses. A refractory metal with unique electrical, chemical, and physical properties that is used mostly as tantalum metal powder in the production of electronic components, mainly tantalum capacitors. Because it has such a very high melting point, it is alloyed with other metals to create alloys that are needed for very high temperature applications, such as metal working equipment and jet
The concentrates are transported to the processors works for chemical processing. Tantalum mineral concentrates may contain from two to more than five different tantalum-bearing minerals from the same mining area.The sale of tantalum mineral concentrates is based on a certified analysis for the tantalum oxide (Ta 2 O 5 ) they contain,with a typical range from 20% to 60% depending on the mine source.
