About 500 kg concentrate with ∼50% tantalite is produced a day from 1200 tons of feed using different mineral processing techniques. Impact of dilution and ore loss on the recovery of concentrate was studied by collecting five samples, 30 kg each from the mine site and tailings.
Our sintered quality tantalum is used for those tricky situations: due to our powder metallurgy production process, sintered quality tantalum (TaS) is particularly fine-grained. As a result, the material is very easy to work and excels due to its excellent surface quality and robust mechanical properties.

The process of mineral separation, sieving and sorting is done manually through washing at streams and rivers. The chemicals used are polluting water bodies and are harmful to aquatic creatures.
Tantalum is obtained from minerals such as columbite, tantalite, and euxenite, often found in combination with niobium. These minerals are primarily found in Australia, Canada, and Brazil. The process of electrolysis or reactions of the carbide with oxide are used to separate niobium from tantalum.
Historically, tantalite has been used in various cultures for its purported protective and grounding qualities. Indigenous tribes in Africa revered tantalite as a talisman, believing it could ward off negative energies and promote emotional stability. ... Through this process of transformation, users can uncover their true potential, leading to ...
The filtration of the digestion slurry, and further processing via solvent extraction using methyl isobutyl ketone (MIBK) or liquid ion exchange using an amine extractant in kerosene, produces highly purified solutions of tantalum and niobium.
