There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
Surface (opencast) mining and deep underground mining are the two basic methods of mining used in South Africa. Approximately 51% of South African coal mining is done underground and about 49% is produced by open-cast techniques.
History of mining in South Africa: Early industrial developments. The first mine to be constructed in what is now South Africa began operations in 1852, a copper project that would go on to form the cornerstone of the town of Springbokfontein, today Springbok, in the Northern Cape province.
Surface mining is a process whereby soil and rock overlying the mineral deposit are removed. There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8).Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock.
