2. Africa in world mining geography

Africa's share of world output of copper and iron ore has decreased while it has increased for bauxite and uranium. The mining specialization of the continent as a whole is, therefore, increasingly based on these latter two minerals, although copper production is still significant. Table 2.4 provides figures for the last 25 years

Mining and Mineral Processing. Metal deposits are mined in a variety of different ways depending on their depth, shape, size, and grade. Relatively large deposits that are quite close to the surface and somewhat regular in shape are mined using open pit mine methods (Figure 20.1). Creating a giant hole in the ground is generally cheaper than making an underground mine, but it is also less
