Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is tantalite. [1]

2024年8月22日 · Coltan is essential to our lives. Explore what coltan is, what it's used for, where and how it’s mined and why it’s a conflict mineral.

2024年8月22日 · You may not have heard of coltan, but it’s a key raw mineral whose components are found in everyday technologies from smartphones to laptops as well as advanced medical equipment.

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.

Coltan or tantalite (short for columbite–tantalites) is a valuable mineral. It is a dull black metallic ore from which the elements niobium and tantalum are got. [1] Tantalum from coltan is used to make tantalum capacitors which are used for mobile phones, personal computers, automotive electronics, and cameras. [2]

2023年9月15日 · However, coltan in the Democratic Republic of Congo, and quickly becoming the rest of Sub-Saharan Africa, is a dangerous material. A majority of Coltan production deposits are under the control of African gangs and rebel troops that mine the ore illegally.

Coltan (short for columbite–tantalite (s)) is an important niobium-tantalum ore. The niobium-dominant mineral in coltan is columbite and the tantalum-dominant mineral is tantalite. Coltan is considered a "conflict mineral".

Coltan is short for Columbite-tantalite – a black tar-like mineral found in major quantities in the Congo. The Congo possesses 64 percent of the world’s coltan. When coltan is refined it becomes a heat resistant powder that can hold a high electric charge.
