1989-1-1 · Processing of ores to produce tantalum and lithium 303 The teeter column is operated to split at a d50 of 300 microns, with the underflow passing to two hutch jigs (I040mm square). Jig concentrate is cleaned by two, two hutch secondary jigs with 600mm square cells to produce a high grade concentrate (25% Sn and 7% Ta205).

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 ...
