The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is tantalite. [1] Tantalum from coltan is used to manufacture tantalum capacitors which are used for mobile phones, personal computers, automotive electronics, and cameras. [2]
Over the past year, the M23 has made rapid advances across the mineral-rich east of DR Congo, taking areas where coltan – the ore from which tantalum is extracted – is mined.
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
Coltan is the most profitable mineral export from the Congo, but it is particularly difficult to track because it is often listed as cassiterite, for which export taxes are lower. Coltan had been illegally extracted and sold via Burundi since 1995, three years before the invasion began. [ 58 ]
Coltan is the colloquial name for the mineral columbite-tantalum ("col-tan"). In the early 21st century coltan mining is associated with human rights violations such as child labour, systematic exploitation of the population by governments or militant groups, exposure to toxic chemicals and other hazards as a result of lax environmental protection, and general safety laws and regulations.

The coltan is a major source of tantalum, which is used in the fabrication of electronic components in computers and mobile phones. In 2002, tin was discovered in the east of the country, but, to date, mining has been done on a small scale. Manono in Central DRC has a significant deposit of lithium and tin with tantalum and niobium and is being ...
The mineral group tantalite [(Fe, Mn)Ta 2 O 6] 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.
