Introduction

The extraction of minerals thus plays an important role in the economic life of many countries in the world. Mineral exports reduce dependence on the sale of agricultural cash crops for foreign exchange.  The mining industry provides employment.  It has stimulated the development of infrastructures such as roads, railways , shops, telephones, electricity supplies and the like to serve the interests of the mining companies and the people who live around the mining areas.
 Africa is rich in mineral wealth.  This includes both metallic and non-metallic minerals.  The most important minerals in Africa include : copper, iron ore, gold, diamonds, petroleum, tin, among others.
Mining plays a very important role in the development of such countries like; South Africa , Nigeria, Libya, Algeria,  Democratic Rep’ of Congo, and Zambia. 
There are however many other African countries that are rich in minerals but they have not been exploited because of remoteness, lack of market, existence in small quantities, lack of capital, power, technology among other factors.
Africa produces more than 60 metal and mineral products and is a major producer of several of the world’s most important minerals and metals including Gold, PGE’s, Diamonds, Uranium, Manganese, Chromium, Nickel, Bauxite and Cobalt. It is interesting to note that Africa's contribution to the world's major metals (copper, lead and zinc) is less than 7%. As a result silver production is low (less than 3% of the world's production) due to the fact that most silver is produced as a by product of lead - zinc and copper mining. Although underexplored, Africa hosts about 30% of the planet's mineral reserves, including 40% of gold, 60% cobalt and 90% of the world's PGM reserves - making it a truly strategic producer of these precious metals.
The increase in exploration and mine development in Africa has been primarily focussed on gold and diamond exploration. Undoubtedly, there is still great scope for these commodities, but riding on the back of improving base metal prices, this sector could see an increase in activities. Mozambique, Nigeria and Madagascar are but a few countries that have tremendous potential for base metal and industrial mineral deposits.
South Africa, Ghana, Zimbabwe, Tanzania, Zambia and the DRC dominate the African Mining industry, whilst countries such as Angola, Sierra Leone, Namibia, Zambia and Botswana rely heavily on the mining industry as a major foreign currency earner. Unfortunately, several African civil wars are funded by (and often caused by) some of these commodities, in particular diamonds.
Major new mines opening in Africa or under development are distributed between South Africa, Namibia, Botswana, Tanzania, and Gabon producing gold, diamonds, niobium products, PGE’s, chrome and base metals. Major discoveries over the last year include the discovery of several potentially diamondiferous kimberlites in Mauritania, and still in the diamond scene, the potential marine deposits in offshore southern Namibia
