Columbite has the same composition and crystal symmetry (orthorhombic) as tantalite. In fact, the two are often grouped together as a semi-singular mineral series called columbite-tantalite or coltan in many mineral guides. However, tantalite has a much greater specific gravity than columbite, more than 8.0 compared to columbite's 5.2.

Induced Roll Separators are a versatile magnetic separator in which a powerful electro-magnet uses an iron circuit to induce a magnetic field in a rotating separation roll, set between fixed and adjustable magnetic poles. The material being treated is fed from a hopper or vibratory feeder at a controlled rate onto a high intensity magnetic roll.
And, the laboratory separator can be used to train operators of the plant size production separators, since the results obtained from varying the operating conditions will produce similar results on the plant size induced roll magnetic separators.
