In Tantalite Valley the proto-mottled metagabbro was emplaced along the axis of the Lineament, This led to partial remobilization of granite gneiss and metasomatic alteration by the latter. Proto-metagabbro, probably a gabbronorite, was then intruded into relatively dry rocks producing a narrow contact aureole and generating granitic partial ...

Tantalite Minerals. Tantalite Minerals are actually well-formed crystals with many faces. The mineral group Tantalite [(Fe, Mn) Ta 2 O 6] is the main source of the element tantalum. it is chemically similar to columbite, and the 2 are regularly grouped together as a semi-singular mineral referred to as coltan or columbite-tantalite in lots of mineral guides.

Tantalite and tantalum. Tantalite is the mineral or ore, and tantalum is the metallic element which can be extracted by chemically processing the ore. Technically, tantalum minerals do not undergo "smelting", although for convenience, this chemical processing is often referred to as smelting in the broader context of 3TG minerals.
