The procedure was repeated through a roll setting of 1.6 mm and a 1.67-mm screen. The combined coarse mica from the three screens comprised 41% of the feed weight and contained 4.9% of the tantalum and 7.9% of the niobium. This lost tantalum and niobium was considered part of the mica lattice rather than unliberated material.
There are many uses of Tantalum metal and below are details on machining Tantalum including welding, grinding, spinning and more! Turning and Milling. In lathe operations, cemented carbide tools with high cutting speeds should be used. The tools should be kept sharp and ground with as much positive rake as the tool can withstand.
Tantalum, one of the rare metals, is an essential material for electronic industry and aerospace technology. Tantalum and niobium has very similar property and are very difficult to separate from each other. As the first step of metal extraction, tantalum and niobium material is enriched to get rich tantalum and niobium concentrate.
Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore, from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium ), and the tantalum …
Depending this data, a variety of different separation strategies can be used to concentrate tantalum and niobium minerals, including grinding, conventional and centrifugal gravity separation, regular or high intensity magnetic separation and advanced flotation techniques.

Tantalum and niobium in arc magmas are depleted relative to REEs, so that Nb/La and Ta/La are lower than in the primitive mantle and in MORBs. Depletion of primitive arc magmas in tantalum and niobium relative to lanthanum and thorium (Figure 14) is ubiquitous (a few niobium-enriched lavas—e.g., Kepezhinskas et al., 1997 —form a distinct anomaly, which will not be discussed in this chapter).

The magnetic tantalum concentrates recovered from each of the three steps were combined into a final tantalum product. Only two flow sheets were evaluated using sample B. Preliminary grinding to -589 µm followed by magnetic separation produced results nearly identical to those obtained when no preliminary grinding was used.
