Tantalite The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalumIt 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 guid However, tantalite has a much greater specific gravity than columbite (80+ compared to columbite's 52)...
Hübnerite Introduction [] Hübnerite is a rare mineral from the rare family wolframite, it is considered to be one of the principle ores of tungsten It is usually identified by the dark color, one direction of perfect cleavage and high specific gravity all serving to distinguish it from other minerals; the first recorded identification of the wolframite family was back in 1948 but it was not added as ....
