The Impact Of Gold Mining In South Africa

Gold mining activities in the Witwatersrand have played a pivotal role in the development and existence of Johannesburg since 1886. Mining made Johannesburg 'the city of gold' and has since been the main driving force behind the history and the economic development of Johannesburg and South Africa as a whole (Gass, 2012).


The water-impermeable linings are used during the conducting of the mine workings within the water-flooded rocks, when, according to the conditions of the operation, there is not acceptable the infiltration of the underground waters through the lining (the shafts of the underground salt mines, the tunnels of the metropolitan subways, and so on).

Environmental impact of iron ore mining

Introduction Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)n(H 2 O)) or siderite (FeCO 3).Roughly 98% of iron ore on the global market is

Impacts of riverine sand mining on freshwater ecosystems

Of the studies reporting the type of mining, most focused on instream mining. Eight focused on the impacts of dry mining (removal of material from an exposed area above the water table, such as on a floodplain), with only two addressing bar skimming (removal of sand and gravel from the surface of exposed river bars).

Ground Water Contamination G

water and certain types of contaminants with rela-tive ease to an aquifer below. Just as ground water generally moves slowly, so do contaminants in ground water. Because of this slow movement, contaminants tend to remain concentrated in the form of a plume(see Figure 1) that flows along the same path as the ground water.


west mini-pit will be left as a void. This change in topography will impact on the surface water flow regime of the area. To minimise the impact of mining operations on surface water draining from the site and consequently on the Lake Disappointment catchment, a number of measures will be adopted during construction and operation of the mine.
