shows the global production of tantalum metal from 1999 to 2021 [3,30]. Because of the benign economic climate between 1999 and 2005, global tantalum production gradually increased to 1916 t. However, Ta production has decreased for several years in a row since 2006, and it was mainly a result of the global financial crisis at that time [3].
