methods of mining gold copper petroleum in africa
Africa has over 30 percent of the world's global mineral reserves. 1. The continent produces over 60 different metals and minerals and has huge potential for exploration and production. 2. There is a considerable history of mining across Africa with artisanal and small scale mining of gold tracing back to the 15th Century. 3The relative depth of the deposit and economic value of the mineral play a key role in determining which method of mining to be used. An underground mine could be as shallow as 300 meters or as deep as 3 kilometers. For example, earth’s deepest underground mine, Mponeng Gold Mine, located in South Africa, has an operating depth beyond 3.1 km.Types of Mining Methods Cummins Inc.
