Processing of ores to produce tantalum and lithium 303 The teeter column is operated to split at a d50 of 300 microns, with the underflow passing to two hutch jigs (I040mm square). Jig concentrate is cleaned by two, two hutch secondary jigs with 600mm square cells to produce a high grade concentrate (25% Sn and 7% Ta205).

The high-grade columbite-tantalite sample was collected from a Ta-Nb mine in Jiangxi, China. It was not pure, thus purification process was required to prepare the pure sample of columbite-tantalite. The sample was purified using a combination of a shaking table and a high-gradient magnetic separator (HGMS).

Tantalum Mining. Tantalum mining and concentrating is a multi-stage process in part because the insitutional grades of tantalum are so low and associated with other minerals such as niobium, tin and lithium. Predominately found in open-pit mines, tantalum is sometimes mined underground as well.
