Keywords: tantalite; beneficiation; magnetic separation; acid leaching 1. Introduction The production of pure tantalum and niobium metals from mineral ore entails the removal of associated impuri-ties and the subsequent separation of these metals from each other. The successful beneficiation of tantalum and niobium ores may vary significantly.
