Minerals in Eastern Congo

Minerals Found in Eastern Democratic Republic of the Congo (DRC)

Eastern Democratic Republic of the Congo — particularly the provinces of North Kivu, South Kivu, and Maniema — is among the most mineral-rich regions in the world. This area is home to a variety of strategically important minerals that fuel global industries, especially in electronics, renewable energy, and defense .

Here are five key minerals found in Eastern Congo :

1. Coltan (Columbite-Tantalite)

Raw coltan ore, often mined in the eastern DRC and processed into tantalum for electronics.

Coltan is one of the most valuable and controversial minerals in the region. It is processed into tantalum , a heat-resistant metal used in capacitors for smartphones, laptops, and military equipment . Eastern Congo holds some of the world’s richest coltan deposits.

2. Tin (Cassiterite)

Cassiterite, the main ore of tin, commonly mined in the Kivu provinces.

Tin is widely used in soldering electronics and manufacturing tinplate for food packaging. Cassiterite — the primary source of tin — is often mined artisanally in the hills of Eastern Congo and has been linked to conflict mineral trade.

3. Tungsten (Wolframite)

Wolframite, a source of tungsten mined in conflict-affected areas of Eastern Congo.

Tungsten is essential for high-strength industrial tools , ammunition , and heat-resistant components . Wolframite, the main ore of tungsten, is commonly extracted in the Kivu regions under poor labor conditions and has historically funded armed groups .

4. Gold

Gold mined from small-scale operations in the forests and rivers of Eastern Congo.

Gold mining is widespread in Eastern Congo, particularly in artisanal and informal settings . The region produces both alluvial gold and vein gold , contributing to local economies and international trade , though often without formal regulation.

5. Cobalt

Cobalt-rich ore from small-scale mines in Eastern Congo, used in electric vehicle batteries.

While most cobalt in the DRC is mined in the Copperbelt region , some deposits are also found in Eastern Congo. Cobalt is a critical mineral for lithium-ion batteries , used in smartphones, laptops, and electric vehicles .
