Environmental impacts of mining can occur at local regional and global scales through direct and indirect mining practices Impacts can result in erosion sinkholes loss of biodiversity or the contamination of soil groundwater and surface water by the chemicals emitted from mining processes These processes also have an impact on the atmosphere from the emissions of Air quality management: a mining perspective F Schwegler Anglo Technical Division South Africa Abstract Air quality management issues relating to mining are mainly centred around particulate impacts These include dust deposition and health impacts associated with PM10 and PM2 5 and the mineralogy and chemical composition of the particles

Effects of Mining on Air

6-8-2012Mining has a great effect on the quality of the air Since mines need to blast through rock to get to an ore dust may be produced in the process Coal mines release methane which contributes to environmental issues because it is a greenhouse gas The methane is sometimes captured but only where it is economically

Environmental impacts of iron ore mining including impact in land water air and economy and environment The Mining is the professional mining equipments manufacturer in Read more environmental impacts of iron ore mining - BINQ Mining Why does mining iron ore cause We will provide you with the best quality products

Mining affects fresh water through heavy use of water in processing ore and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments Increasingly human activities such as mining threaten the water sources on which we all depend

Environmental impacts of mining can occur at local regional and global scales through direct and indirect mining practices Impacts can result in erosion sinkholes loss of biodiversity or the contamination of soil groundwater and surface water by the chemicals emitted from mining processes These processes also have an impact on the atmosphere from the emissions of

While LTV mined taconite at the site a layer of the Duluth Complex lay on top of the iron ore along one end of the mine In exposing the iron ore LTV removed an estimated 50 million tons of sulfide-bearing rock that it stockpiled at the mine site where it remains to this day

what are the environmental impacts of iron ore mining IMPACTS OF IRON ORE MINING ON WATER QUALITY AND THE However mining of iron ore has copious negative impacts on the environment As the mining method is usually open cast it degrades natural landscapes surface and ground water Flora and Fauna ore extraction mineral concentration

environmental impacts of iron ore mining The Enviromental impacts Of Mining Iron Ore by M C on Prezi We need iron ore products in our daily lives however we need to understand the negative impacts of mining and think of ways to reduce the environmental impacts by proper planning and reducing our Get price

Steel production environmental impact

6 5% of CO2 emissions derive from iron and steel production (IEA 2010) 1 Mineral Extraction Iron ore Iron doesn't occur naturally Being highly reactive it combines easily with other minerals to form ores Those with the highest iron content are found near the surface of the earth and are relatively easy to mine

According to the report flooding water quality and water shortages are the predominant cause of impacts which resulted in an increase of operating costs for more than half of those reporting detrimental impacts Just a quick search of the news highlights many incidences of mining operations around the world being affected by water in some way

Other wastes from mining may be in the form of water and air pollution The majority of air emissions associated with the mining industry include dust oxides of nitrogen sulphur dioxide and carbon monoxide Some of these come from mining vehicles and on-site plant machinery Water quality may be affected by:

A proposal is in development to create an open pit iron mine between Upson and Mellen in the coming years As this mining proposal develops we are following closely to gauge how a project like this will affect our watershed community Like many of you we are interested in the potential economic benefits this may bring
