Tantalite forms a solid solution series with Columbite known as the Columbite-Tantalite series. Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum.
The processing of tantalite-columbite ore is complex due to its low content and sophisticated composition. Usually, the enrichment flow sheet of tantalite-columbite covers rough concentration and fine selection. And for different tantalite-columbite mines, the specific flow sheet can be different.

due to the refractory nature of tantalite, and XRF due to the typically low natural tantalum abundances. Our laboratories use fusion ICP-OES or fusion ICP-MS to ensure both a low detection limit and total analysis. ORES, CONCENTRATES AND HEAVY MINERAL SEPARATES High-grade ore and metallurgical products are readily analyzed by automated borate
Niobium and tantalum mineral deposits are most com-monly associated with igneous rocks3, including granites, pegmatites4, syenites5 and carbonatites6. Some secondary deposits, where niobium- and tantalum-bearing minerals have been concentrated by weathering and sedimentary processes, are also known (see Table 3 and Figure 3 at the

Tantalite ore was digested using molten ammonium bifluoride. Niobium and tantalum were extracted using octanol as extractant. Addition of H 2 SO 4 improves the separation of niobium and tantalum. Extraction with 2-octanol is almost similar to extraction with 1-octanol. Two and three stages were sufficient for the extraction of Ta and Nb respectively.
Fractional crystallization: separates ore and non-ore minerals according to their crystallization temperature. As early crystallizing minerals form from magma, they incorporate certain elements, some of which are metals. These crystals may settle onto the bottom of the intrusion, concentrating ore .
Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is nonreactive and nonirritating to body tissues.
