Tantalum
The Democratic Republic of Congo in particular contains large deposits of a mineral containing a mix of tantalum and niobium compounds, called columbite-tantalite, colloquially known as coltan. Profits from coltan mining have helped fund the opposing sides in the DRC's appalling civil war, which has killed more than 5 million people since 1998.
Coltan | Earth Sciences Museum
Kathy Feick. Coltan is short for columbite-tantalite, a dull metallic ore. When refined, coltan becomes a heat resistant powder, metallic tantalum, which has unique properties for storing electrical charge. Coltan occurs in granitic pegmatites, pockets where the deep seated molten rock crystallized last. Pegmatites contain many rare metals, as ...

Tantalite vs. Tantalum — What's the Difference?
Tantalite. The mineral group tantalite [ (Fe, Mn)Ta2O6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) 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.
Tantalum Processing | TIC
Tantalum metal powder, including the precursor to capacitor grade powder, is generally produced by the sodium reduction of the potassium tantalum fluoride in a molten salt system at high temperature. The metal can also be produced by the carbon or aluminium reduction of the oxide or the hydrogen or alkaline earth reduction of tantalum chloride.

A review on extractive metallurgy of tantalum and niobium
The pre-treatment of colombo-tantalite ores involves common size reduction operations such as crushing and grinding coupled with size classification. The targeted final granulometry by each of these operations is mainly dictated by the subsequent down-stream operations and the need for an early stage elimination of deleterious elements.
Engineering Physics Questions and Answers
Explanation: Mechanical crushing is the method sued in the preparation of metal oxide nano crystals. In this method, small balls are allowed to rotate inside a drum and are made to fall on a solid with a high gravitational force that crushes the solid into nano-crystals. Thus iron nitriles nano-crystal can be made by using mechanical crushing.
