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 dissolve as complex fluorides, and numerous …

Most tantalum mines are open pit whereas some are underground. The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum. The ore is then concentrated at or near the mine site, to increase the weight of tantalum oxide and niobium after which the material is concentrated through ...

Jan 01, 1989· Abstract. Although tantalum and lithium are chemically quite different elements, they both occur in the Greenbushes pegmatite in adjacent mineralogical zones. Tantalum occurs as complex pentoxide minerals in association with niobium and tin. It is recovered by gravity separation followed by pyrometallurgical processes, and then …

It is estimated to produce an annual average of 236,532t of technical and chemical-grade spodumene concentrates and 429t of tantalite concentrate. The ore will undergo three-stage crushing and a single-stage grinding in a ball mill, followed by magnetic separation to retrieve tantalum, mica flotation and spodumene flotation. Read More

The mineral group tantalite [Ta2O6] is the primary source of the chemical element tantalum, a corrosion resistant metal. 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 …
