Tantalum Processing TIC

Processing: extraction and refining. K2TaF7 Process, H.C. Starck GmbH, (Gerald Baehnish) The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures.

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).

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 alloys and tantalum powders for capacitor manufacture.
