The mineral group tantalite is the primary source of the chemical element tantalum, a corrosion resistant metal. 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 .

The price of the tantalite is very much dependent on the demand as well. The price of tantalite ore rose from about $75 per kilo in 2010 to more than $270 per kilo on 2011 and 2012. But the price has dropped since then. However, some experts point to expected growth in the electronics, aerospace, and power industry to boost the price …

Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low grade and contain only 0.01 to 1 percent tantalum pentoxide, which is equivalent to 0.1 to 10 kilograms per metric ton. As a result, to produce concentrates of tantalum, tantalite ore must be separated from other minerals in the ore.

Most tantalum mines are open pit whereas some are underground. The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum. The ore is then concentrated at or near the mine site, to increase the weight of tantalum oxide and niobium after which the material is concentrated through ...

About Tantalite Hide. Formula: (Mn,Fe) (Ta,Nb)2O6. An obsolete group name for minerals with the general formula (Mn,Fe) (Ta,Nb) 2 O 6, equivalent to the Tantalite- (Fe)-Tantalite- (Mn) Series. Generally mangan-dominant members are more abundant in nature. Many specimens called tantalite actually belong to the columbite series or tapiolite series.

The decrease of Nb/Ta in columbite– tantalite and of Zr/Hf in zircon is consistent with fractionation of a silicate melt (Linnen and Keppler, 1997, 2002). The most contentious question concerning the magmatic controls of mineralization is how the ore minerals, primarily columbite–tantalite, become saturated.
