The development of tantalum capacitor (TC) industry is associated with the production of one technology metal-tantalum (Ta). The recycling of waste tantalum capacitors (WTCs) is an important strategy for the sustainable development of tantalum related industries. A cryogenic crushing-alkaline calcin...
