    Coltan

    A mineral ore composed of columbite and tantalite, from which the element tantalum is extracted for use in electronics.

    Definition & Context

    Coltan (columbo-tantalite) is a metallic ore from which tantalum is refined. Tantalum is used in capacitors found in virtually all smartphones, laptops, and electronic devices, as well as in aerospace and medical equipment. The DRC holds approximately 60% of the world's known coltan reserves, primarily in the eastern provinces of North and South Kivu. Coltan mining in the DRC has been associated with conflict financing, leading to international regulations including the Dodd-Frank Act (Section 1502) and EU Conflict Minerals Regulation.

    Key Facts

    • DRC holds ~60% of world's coltan reserves
    • Primary source provinces: North Kivu, South Kivu, Maniema
    • Used in capacitors for smartphones, laptops, aerospace
    • Classified as "strategic mineral" under 2018 Mining Code
    • Subject to ITSCI traceability requirements
    • Subject to Dodd-Frank Act Section 1502 and EU regulations

    Global Context

    Coltan has been at the center of global debates about conflict minerals and responsible sourcing. International frameworks like the OECD Due Diligence Guidance, the Dodd-Frank Act, and the EU Conflict Minerals Regulation require companies to trace their tantalum supply chains. The DRC's formalization efforts aim to bring artisanal coltan mining into the legal economy.

    Frequently Asked Questions

    What is coltan used for?

    Coltan is refined to produce tantalum, which is used in capacitors for smartphones, laptops, gaming consoles, and other electronics. It is also used in aerospace components and surgical implants.

    Why is DRC coltan controversial?

    DRC coltan mining, particularly in eastern provinces, has been linked to conflict financing by armed groups. This led to international regulations requiring supply chain traceability and responsible sourcing certification.
