10 Most Important Precious Minerals and Metals Found in Africa

Africa is rich in a variety of minerals, metals, and oil resources. The continent holds 30 percent of the mineral resources on earth and houses 5 of the top 30 oil-producing countries globally.

The continent has abundant mineral and metal reserves and also ranks among the primary producers of these resources.

The bountiful natural resources in Africa made the region the fastest-growing foreign investment in the world.

North Africa holds natural gas deposits, while Sub-Sahara Africa has mineral resources like gold, copper, coltan, nuclear/uranium ore, and more.

Generally speaking, there is an uneven distribution of precious minerals and metals in Africa.

Still, most of the deposits can occur across Western Africa, Central Africa, and Southern Africa, and some of these natural resources are still untapped.

Let’s explore the ten most important precious minerals and metals found in Africa arranged in descending order based on their place in global production while also tracing their numerous deposits and uses.
