Oct 12 2020 Mining waste has different characteristics depending on the type of ore being mined Our Swedish ores can be roughly divided into oxidic and sulphidic ores The oxidic ores predominate in Norrbottens iron ore field while the sulphidic ores are more prominent in eg the Skellefte field in Sep 06 2012 Iron is an integral part of the natural environment and many important chemical reactions involve changes in iron that are caused by an electron being transferred to the iron from other minerals water or biological agents Electron transfer to iron III oxides creates iron II sites in the mineral But the iron II site is not fixed as the electron can hop to other sites

Sep 01 2016 Regarding the environmental impact on Mineral Extraction 007 one would expect to observe a higher impact considering the high amounts of iron ore consumed but this was not the case This could indicate that impact on mineral extraction was low in comparison to impacts that are directly associated with the production process of sinter Environmental impacts of mining largely depend on the methods used and the geological context that governs how easily the minerals can be separated from the ore material Unlike gold mining which often uses potentially toxic chemicals such as mercury and cyanide gemstone mining does not depend on chemicals for extraction of the rough material
