tantalite mining infomation


Niobium and tantalum | U.S. Geological Survey

Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of high-strength steel alloys …

Tantalite - Wikipedia

The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum.It 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).
