Environmental Impacts Diamond mining in South africa
The openpit mining means that large amounts of excess rock, sand and soil and processed Kimberlite can accumulate in areas and just stay there as there is not much that you can do with it. This is what is happening in some South African mines and it is a direct and unsustainable impact on the environment.

What Is Open Cast Mining? |
Open cast mining is a type of surface mining in which mineral resources are removed from the earth through large holes or pits dug into the surface. The term "open cast mining" is used most commonly in Great Britain. In the United States, open cast mining is usually called openpit or opencut mining.

Extraction of Resources | Geology
OpenPit Mining. Openpit mining, or opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining.
Coal Minerals Council South Africa
Coal mining's advent in South Africa can best be traced to the start of gold mining in the late 19 th century, particularly on the Witwatersrand, with the first coal in appreciable tonnages being extracted on the Highveld coal field close to the nascent Witwatersrand gold mines. However, demand began to grow, slowly at first but then ...

Manganese Mining and Processing: Everything you Need to Know
Most manganese mining occurs in open pits. Although there are processes in place to mine manganese nodules in the ocean floor, they cannot complete with landbased mining production. Once the ore is mined, it's transferred to a processing plant for electrolytic processing or smelting.
iron | Element, Occurrence, Compounds |
Occurrence, uses, and properties. Iron makes up 5 percent of Earth's crust and is second in abundance to aluminum among the metals and fourth in abundance behind oxygen, silicon, and aluminum among the, which is the chief constituent of Earth's core, is the most abundant element in Earth as a whole (about 35 percent) and is relatively plentiful in the Sun and other stars.
Coal Mining Methods
Once all coal is gone from the current strip, a new strip is created next to it. Open cast coal mining recovers a greater proportion (up to 90 percent) of the coal deposit than underground methods. Globally, about 40 percent of coal is produced by surface mining.
Copper mining. From ore to copper.
