Blog The Big Tantalum Recovery

The process was repeated four times. After each run, the columns would take 3 days to cool enough to allow a person to go inside and collect the Tantalum Oxide. When the 4 month long project was completed, we recovered almost 9 MT of Tantalum Oxide. Not only was the remaining 100 tons of steel sold for scrap, but the recovery of hundreds of

A primary processor is generally also able to process secondary concentrates (columbite or struverite), synthetic concentrates and/or scrap. The products of a primary processor may be anything from the most common tantalum intermediate 'K-salt' (K 2 TaF 7 ), through to high purity oxides or capacitor grade tantalum metal powder.

Tantalite Wikipedia

The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum.It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides. However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2).
