Tantalum grades tend to be significantly lower for primary lithium mines where tantalum is a byproduct. 2 Although DRC regulations define variable tantalum (in combination with niobium) grade ranges for its coltan export concentrates, a strict enforcement of credible grade controls by state services has been difficult to establish in

Tantalum secondary raw materials are mostly preconsumer scrap that was generated during the manufacture of Tacontaining electronic components as well as from cemented carbide and superalloy scrap. Figure 10.9 demonstrates the considerable amounts of those internal material circuits comparing to external flows (EOL scrap). The unoxidized tantalum scrap
Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low grade and contain only 0.01 to 1 percent tantalum pentoxide, which is equivalent to 0.1 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.
Tantalum has a unique set of properties that make it useful in a number of diverse applications. The ability of the metal to store and release electrical energy makes it ideally suited for use in certain
Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950. Niobium in the form of ferroniobium is used worldwide, mostly as an alloying element in

Tantalum minerals with over 70 different chemical compositions have been identified. Those of greatest economic importance are tantalite, microlite,and wodginite; however, it is common practice to name any tantalumcontaining mineral concentrate as 'tantalite' primarily because it will be processed for the tantalum values and is sold on that basis.The

Tantalumtungsten (TaW) excels due to its good mechanical properties and excellent corrosion resistance. We add between 2.5 and 10 percent by weight of tungsten to pure tantalum. Although the resulting alloy is up to

used to treat this slag will require a selective diss olution of the matrix phase to concentrate the tantalum and niobium oxides mostly contained in the dendritic phase (Allain, 1993). Table 1.

10. A method for the dissolution and purification of tantalum concentrates, comprising: (a) combining a tantalum concentrate, a fluoridecontaining compound, and sulfuric acid to form a solution containing tantalum values and impurities; the fluoridecontaining compound being selected from NH4HF2, NaF, KF, CaF2, or a combination
