    The China tantalite-columbite content is generally low with its crisp nature and big density, so the process for this kind of ore needs stage milling and stage separation. Here is a case of pegmatite mineral project to share with you. Considering the inlay nature of the ore, stage milling and stage separation has been used.

    A Review of NiobiumTantalum Separation in Hydrometallurgy

    Niobium and tantalum are chemically similar and are associated with each other in nature which makes it very difficult to separate. For many years, the separation of tantalum from niobium involved the fractional crystallization of potassium heptafluorotantalate away from potassium oxypentafluoroniobate monohydrate, this method has been supplanted by solvent extraction from fluoride-containing ...
