processing of ores to produce tantalum and lithium

Tantalum occurs as complex pentoxide minerals in association with niobium and tin. It is recovered by gravity separation followed by pyrometallurgical processes, and then solvent extraction to produce Ta 2 O 5 as the starting material for carbide production, or K 2 TaF 7 as the starting material for the production of tantalum metal for super
