The mineral group tantalite [(Fe, Mn)Ta2O6] is the primary source of the chemical element tantalum. It is chemically similar to columbite, and the two are often grouped together as a semisingular mineral called coltan or "columbitetantalite" in many mineral, tantalite has a much greater specific gravity than columbite (+ compared to columbite's ).
Gold nuggets found on Earth range from sizeable nuggets through tiny grains in alluvial (river) deposits to microscopic pieces in rocks. Commercially, gold is purified by cyaniding, amalgamating with mercury, or smelting processes. Further refining, which produces nearly pure gold, is usually by electrolysis.
