Processing Tantalum Ore

Coltan

Coltan

Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobiumdominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalumdominant mineral is the tantalite.. Tantalum from coltan is used to manufacture tantalum capacitors which ...

Mineral Resource of the Month: Tantalum

Mineral Resource of the Month: Tantalum

Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low grade and contain only to 1 percent tantalum pentoxide, which is equivalent to to 10 kilograms per metric ton. As a result, to produce concentrates of tantalum, tantalite ore must be separated from other minerals in the ore.

Most of the TaNb ores in China occur in altered granites, and TaNb minerals occur in these granites as accessory minerals. This type of TaNb ores are characterised by whole mineralised granite mass, large reserves, low grade of tantalum and niobium, less economic minerals, complex mineralogy, difficulty in separation and concentration of TaNb minerals and high operating cost of ore dressing.

 · Tantalum ores are found in Australia, Zaire, Brazil, Mozambique, Thailand, Portugal, Nigeria, and Canada. A complied process is required to remove tantalum from the ore, as tantalum always occurs with niobium. Tantalum is estimated to occur at an abundance of about 1 ppm or 2 ppm in the Earth's crust.

Economic Geology of Niobium and Tantalum

Economic Geology of Niobium and Tantalum

Tantalum ore has characteristically grades of about % Ta 2 O 5, generally as a coproduct of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hardrock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.

In the ore deposits tantalum appears in solid solution with niobium in complex oxides, which forms low grade aggregates which need to be processed by means of a separation process. Tantalum ores characterised here belong to alluvial placers of pegmatitic origin loed in the Bolivian Amazon Craton and to leocogranites of Penuota, in Spain.

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.
