Africa as a major mineral powerhouse

By: Keziah Biya

Africa remains one of the world’s richest regions when it comes to minerals and natural resources. The continent holds very large shares of global reserves for many critical and strategic commodities, including platinum group metals (PGMs), chromium, manganese, cobalt, diamonds, bauxite, and many others.

According to recent data, Africa produces a large fraction of the world’s supply of certain minerals and metals: e.g. a dominant share of global platinum, manganese, chromium, and substantial shares of cobalt, diamonds, bauxite, gold, copper, lithium, uranium and graphite among others.

Yet, despite this wealth, the continent faces challenges: many resources are exported as raw materials, rather than processed locally. Infrastructure gaps, policy uncertainty, and high operational costs continue to hamper transformation of mineral wealth into broader economic development.

 The “Big Five” mining countries: South Africa, Nigeria, Algeria, Angola, Libya

These five countries are often identified as the top contributors to Africa’s mineral wealth,  together accounting for over two-thirds of the continent’s mineral output/value.

Here’s a breakdown per country:

South Africa

Leads the continent in mineral wealth: estimates put its annual mineral-resource revenue (all minerals combined) at around US$ 125 billion per year.

Produces a wide range of minerals: gold, platinum-group metals, diamonds, coal, iron ore, chromium among others.

Globally, South Africa remains a major player: leading producer of platinum, manganese, chromium; among the top producers of coal, iron ore, titanium, zirconium, and more.

Nigeria

Estimated to generate around US$ 52–53 billion per year from minerals/oil.

Nigeria’s mineral wealth is not limited to its famous oil: the country also has significant deposits of gold, iron ore, columbite, and other minerals.

However, as in many African mining nations, the sector is “underdeveloped,” meaning many mineral deposits remain under-exploited.

Algeria

Generates around US$ 38–39 billion per year in mineral/hydrocarbon revenue (the exact mix is heavily skewed toward hydrocarbons).

Though mostly known for oil and natural gas, Algeria has been flagged as having “potential” for further mineral development beyond hydrocarbons, especially if non-oil mineral deposits are more systematically developed.

Angola

Annual mineral/oil revenues estimated at around US$ 32 billion.

Angola’s resource base includes oil, diamonds, gold, and other minerals.

As with many other African nations, there is likely room for growth, particularly if infrastructure, regulation, and mining investments are improved.

Libya

Estimated mineral (and hydrocarbon) wealth: about US$ 27 billion per year.

Libya’s strengths are largely in oil, but it also possesses industrial minerals (e.g. salt, cement-clay related materials) and other extractives.

Key Challenges & Structural Issues

Under-development despite wealth: In many of these countries, the mining sectors remain underdeveloped. That is, even with large reserves, the full potential is often unexploited because of limited infrastructure, insufficient investment, or regulatory challenges.

Export of raw materials rather than value-added products: A common issue is that many African nations export raw ores instead of processing them locally. This means much of the value and jobs that come from processing and manufacturing is lost.

Dependence on commodities & price volatility: Because many African economies rely heavily on mineral exports (especially oil and metals), they are vulnerable to fluctuations in global commodity prices. This can lead to boom-and-bust cycles.

Need for regulatory, infrastructural and institutional improvements: To fully benefit from mineral wealth, there’s a need for better governance, investment in infrastructure (roads, rail, power), fair policies, and incentives to process minerals domestically.

 What This Means (For Africa and for Nigeria)

Africa’s vast mineral wealth, from platinum to iron ore to oil,  gives it real potential to drive economic growth, industrialisation, and export-led development.

For countries like Nigeria (where you are), these resources represent major opportunities beyond just oil: if mining is properly developed, diversified, and regulated, mineral wealth could become a big driver of jobs, revenue and economic diversification.

But to harness this potential, it’s important for governments and stakeholders to invest in infrastructure, create transparent and stable regulation, and shift from just exporting raw materials toward processing, value-addition, and sustainable mining.

The more African countries manage to do this, and collaborate (domestically and across borders), the more likely it is that the continent’s mineral wealth will translate into long-term improvements in living standards, industrial capacity, and economic resilience.

But to unlock that potential sustainably, there needs to be better governance, investment in processing/refining, infrastructure development, and policies that ensure mining benefits local communities and economies, not just multinational firms or foreign export profits.
