In its elemental form, tantalum has a grayish blue appearance. Tantalum is found in the minerals tantalite, microlite, wodginite, euxenite, and polycrase. Due to the close relation of tantalum to niobium in the periodic table, Tantalum's name originates from the Greek word Tantalos meaning Father of Niobe in Greek mythology.
Tantalum material exports from and imports to the united States included tantalum metal, ores, powders, and waste and scrap. In 2016, the united States exported tantalum materials valued at $154 million (about 12% less than that of 2015) and imported tantalum materials valued at $197 million (about 28% less than that of 2015) (table 2).
The invention is concerned with the recovery and separation of tantalum and/or niobium from a solution of these elements in aqueous mineral acid, preferably sulfuric acid. The element or elements is/are extracted from the acid solution thereof by means of an amine, preferably a tertiary, long-chained alkyl amine, in the presence of hydrogen peroxide and of fluoride ions.
