These results indicate that efforts to reduce the increased greenhouse gas emissions from mining and mineral processing, anticipated in the future as a result of falling ore grades and more finergrained deposits, should focus on loading and hauling for iron ore and bauxite, while for copper ore the focus should be on grinding....
What are the effects of iron mining? | Yahoo Answers
Aug 11, 2011· In general, overgeneralizing is used for iron extraction, which does upset the Earth (because the ore has to be dug out of the ground), the ore and whatever rocks the iron ore is in are put into tailing piles and then various chemical processes are used to extract the iron ore itself....
Environmental Impacts of Mining
Mining unearths large amounts of ore that contains precious metals, such as gold and silver, as well as iron and other sulfides. When sulfides in the ore are exposed to water and air, sulfuric acid is created, which can seep from mines and waste rock piles into streams, rivers, and groundwater. This seepage is called acid mine drainage....

Jun 17, 2017· Environmental Impact of Metal Extraction. Now, an abundance of mercury in the soil and water has led to an increased mercury level in fish, which is very toxic not only to animals but to humans as well. The same is said of metal extraction. Metal extraction can drastically affect air quality in the surrounding areas,......
Appendix 2: Environmental and Social Impacts of Mining
Gold and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003)....

The Environmental Impact of Aluminum (And Why it's Still ...
Bauxite is collected from the ground in an openpit mining operation. It doesn't sit very deeply in the earth's crust, so some energy can be saved on drilling. However, to recover all the aluminum in an area, swaths of land must be bulldozed to reveal the dirt and ore underneath. Once collected, the bauxite ore has to be refined. Facilities use chemical processes to weed out other compounds like silica ....
