problems Rustenburg''s recent history has been closely linked with platinum. Although platinum had been discovered in the early 1900s, it was only in 1925 that platinum mining in the district became financially viable when sufficient deposits were discovered.
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 ...
The health and environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and fluegas desulfurization sludge, that ...
2. Assessment of risks linked to mining waste. The notion of environmental impact of mining activities is only fully meaningful if it includes a change in the initial environmental parameters, due to such activities. These parameters, which govern the "quality of the environment", may have several
In the last 12 months, natural disasters such as earthquakes and floods have had a real impact on mining companies, as have climate change and water scarcity issues. Factoring the potential effects of climate change is of particular relevance to the mining industry when undertaking environmental risk assessments (as well as integrating them ...
Feb 01, 2013· The current turbulence in the mining industry in South Africa has its roots in several different factors. First, the fall in global demand for platinum and other minerals due to recession; second, the consequences of the Marikana disaster in destabilising labour relations; and third, the structural character of our mining industry. A great deal has been written about the first two factors, so ...
Mining leaves an eyesore on the land. By ripping open mountains to extract the ores within, it sometimes leaves areas unusable after the mining companies have left. We can''t go on this way, and politicians agree. It''s why mining companies are working to reduce the environmental impact of mining through green mining processes.
