Tantalum has a wide range of industrial uses. It is used as an alloying element in super-alloys for jet turbine blades (Damm, 2018; Geological Survey, 2022).Because of its high corrosion resistance, tantalum is used in chemical processing equipment (Damm, 2018).Tantalum is used for prosthetic devices, hip joints etc., because of its good biocompatibility (Nassar, 2017).

Tantalum is a grey, heavy and very hard metal with a melting point of over 3000 degrees Celsius. It is classified as a "refractory" metal, which means it can sustain high temperatures and resist corrosion. It is a good conductor of heat and electricity, which makes it useful in various electronics. Pure tantalum can be drawn into fine wire filament, which is used …
