How To Concentrate Tantalite

TANTALUM, TIN AND TUNGSTEN

As a consequence tantalum recoveries and concentrate grades are much lower than for mineral sands, typically 60% and 30% respectively, while tin and tungsten are generally higher, although still not as high as mineral sands. A typical tantalum / tin / tungsten crushing circuit consists of a grizzly screen which is fed from a run of mine (ROM

Upgrading Tantalum Concentrates - 911

One used for a titanium-niobium-tantalum-rare earth mineral concentrate involves blending the crushed concentrate with coke and passing this through a chlorination stage which separates out the rare earths and other elements including most of the thorium. The resulting titanium-niobium-tantalum oxichloride gas is dropped in temperature which causes the iron, thorium and alkali metals to precipitate out. The

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).

Tantalum Processing | TIC

Processing: extraction and refining. The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures. This causes the tantalum and niobium values to
