the extraction of niobium and tantalum by hydrofluoric acid. A number of hy-drometallurgical processing schemes [2-61 have been developed for treatment of tin slags. From the limited information available in the literature, it appears that hydrometallurgical processing of low grade (<10% Niobium + tantalum oxide) 100
The processing of tantalum into anode materials, especially high capacitance value per gram dielectrics, is a technology that is largely focused in Japan, Germany, the U.S. and the republic of Kazakhstan.

Tantalum supply is majorly from primary mining (artisanal and small-scale mining accounting for 48% and conventional mining 25%), tin slags (7%), secondary recycling (20%) and inventories and stockpiles, as reported in 2020 . Tantalum belongs to the critical metal category with recycling rate of less than 1% .
3 Tantalum. Tantalum is a relatively rare element, and commercial quantities are found in Australia, Brazil, Canada, and Africa. Tantalum is also present in tin-bearing ores and remains in the slag from tin refinement. Tin processing is, in fact, the primary source of commercial tantalum, since the processing of other sources are much more costly.
cases, tantalum minerals are separated from the concentrate using a dry method. Most of the tantalum, how ever, is smelted along with tin ore concentrate and then enriched in a …

Metallurgical-grade tantalum powder is used in various processed tantalum materials or alloying agents in powder metallurgy. It is mostly produced by using potassium fluotantalate in sodiothermic reduction, carbothermic reduction, or electrolysis process. It is a dark grey powder. Its Fisher particle size is 5.0–13.0 μm.

Tantalum is the more interesting and valuable of the two metals and will likely drive any possible recovery, and the impacts of the process are thereby allocated more heavily to tantalum. As a result of this, the allocated impacts of the coproduction of niobium are smaller than primary production from coltan ore for all of the studied raw ...

industrial process. Such slags can already be considered as an eventual and important source of refractory metals as tantalum and niobium.4 Indeed, tantalum production from tin slag in Thailand and Malaysia represented 13% of the total tantalum production in 2010.6 Therefore, the circularity of this kind of metals is specially important.7
