    Tantalum is estimated to make up about 1 ppm or 2 ppm of the Earth's crust by weight. There are many species of tantalum minerals, only some of which are so far being used by industry as raw materials: tantalite (a series consisting of tantalite-(Fe), tantalite-(Mn) and tantalite-(Mg)) microlite (now a group name), wodginite, euxenite (actually euxenite-(Y)), and polycrase (actually polycrase-(Y)). Tantalite (Fe, Mn)Ta2O6 is the most important mineral for tantalum extraction. Tantalite ha

  • 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.
