Mining and mineral processing The lithosphere Siyavula

Once a suitably sized deposit of a mineral has been found, mining can begin. In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. Mining is largely divided into surface and underground mining. Minerals are often found in river beds, beach sands and other sandy areas.

Environmental AS The lithosphere (Mineral resources

Mineral deposits are likely to be mined if sufficiently profitable with no prohibitive environmental, political or social problems. Profitability of mining is simply the difference between the income from selling the processed mineral and the total costs of extracting and processing it.

Consequences of over Exploitation of Mineral Resources

Each step in mining and processing operations produces large quantities of waste materials. As most of today’s mines are simple surface excavations, the first task of a miner is to remove whatever lies over the mineral deposit, be it a mountain, a forest or an agricultural field. Under­ground mining with a system of shaft and tunnels does not produce as much waste as open cast mining does.
