The first step is to produce a uranium-free product which can be sold to the European and North American markets. The next step is to produce tantalum and niobium compounds such as K 2 TaF 7 and K 2 NbF 7, and the final step will be to produce Ta 2 O 5 and Nb 2 O 5 powder. This will significantly increase the earnings.

6.65 - 7.95. Crystal System: Orthorhombic. Member of: Columbite Group. Name: From ferrous iron content and the Greek mythological Tantalus, for the difficulty of dissolving the mineral. The original material with Fe>Mn was called Tantalite, subsequent name changes recognized the compositional variability of the series.
and tantalite ore is being mined by open pit mining using conventional truck/excavators. The current strip ratio is around 15, which has resulted in production cash costs of around US$660/t in the most recent quarter. ... the final shipped product, lithium concentrates and tantalum.
Metallurgical products include sheets, plates, welded tubes, rods, and wires. These products account for about 8 to 11 percent of tantalum consumption (Roskill Information Services Ltd., 2012). Figure 2 shows the relationship among refined tantalum products, intermediate manufactured products, and final (consumer) goods.

Treating tantalite from a tailings operation in the DRC, spiral technology has performed massive bulk reduction and upgrading, while shaking tables clean the final product. "This allows existing downstream processes to become more productive, and to ramp up production by maximising recoveries and reducing rand per ton costs," he says.
Conflict resources are natural resources extracted in a conflict zone and sold to perpetuate the fighting.

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.
