In Africa you will only be allowed to upgrade Coltan to a saleable grade using whatever method you choose but most common would beGravity Concentration. You would not be allowed to refineTantalumand Niobium in Africa as it involves chemicals which are not permissible anywhere in …

It is recovered bygravityseparation followed by pyrometallurgicalprocesses, and then solvent extraction toproduceTa 2O 5 as the starting material for carbideproduction, or K 2TaF 7 as the starting material for theproductionoftantalum metalfor super alloys and tantalum powders for capacitor manufacture.

Tantalumcomes from theprocessingand refining oftantalite.Tantaliteis the common name for any mineralorecontaining tantalum. Most tantalum mines are open pit; some are underground. Theprocessof miningtantaluminvolves blasting, crushing and transporting the resultingoreto begin theprocessof freeing the tantalum.

Toextract tantalumfromtantaliteat the mine site, the mineral is first crushed and concentrated using conventional andcentrifugal gravity separation, a magnetic separation and advanced flotation before furtherprocessing.

Processing: extraction and refining K 2 TaF 7Process, H.C. Starck GmbH, (Gerald Baehnish) The extraction and refining oftantalum, including the separation from niobium in these varioustantalum-containingmineral concentrates, is generally accomplished bytreatingtheoreswith a mixture of hydrofluoric and sulfuric acids at elevated temperatures.

Metallurgical Processing. Mineralogical data provides the grain size and textural parameters needed to establish and optimize a metallurgical flowsheet. Depending this data, a variety of different separation strategies can be used to concentratetantalumand niobium minerals, including grinding, conventional andcentrifugal gravity separation,...
