How Tantalum Is Mined | Sciencing

Apr 24, 2017 . Tantalum is a grey, heavy and very hard metal with a melting point of over 3000 degrees Celsius. It is classified as a "refractory" metal, which means it can sustain high temperatures and resist corrosion. It is a good conductor of heat and electricity, which makes it useful in various electronics. Pure tantalum.

Exploration Strategy and Methods for Pegmatite Deposits of Tantalum

Abstract. Economic concentrations of tantalum in granitic pegmatites are restricted to the rare-element class of orogenic pegmatite associations. These pegmatites are particularly abundant in the Kenoran greenstone belts and parametasedimentary gneissic troughs, Hudsonian cratonic margins and rifts, and Variscan fold.

Tantalite: The mineral columbite-tantalite information and pictures

Tantalite forms a solid solution series with Columbite known as the Columbite-Tantalite series. Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum.
