Coltan [Columbite-Tantalites] Ore

However, tantalite has a much greater specific gravity than columbite, more than 8.0 compared to columbite''s 5.2. REFINING The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures.

Tantalite

The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides.However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite''s 5.2).

Small Mineral Processing Plant Design

 · Today, however, more effort is given to producing ores which usually do not occur in large deposits, such as columbite-tantalite, beryl and others which are becoming more important. The increasing use of portable and semi-portable mills—which offer mobility with a minimum of cost, time and loss of initial investment—has played a very important part in recovering these ores.
