  • How Tantalum Is Mined Sciencing

    Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum. The ore is then concentrated at or near the mine site, to increase the percentage (by weight) of tantalum oxide and niobium.

    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 semi singular mineral called coltan or quot;columbite tantalitequot; in many mineral guides. However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2). Iron rich tantalite is the mineral tantalite (Fe) or ferrotantalite and manganese rich is tantalite (Mn) or manganotantalite.
