Increased mining activity of iron ore has led to the generation of voluminous wastes of various nature especially during the different stages of its extraction and production The improper disposal of such waste causes negative impact on the environment One such waste which is generated during the beneficiation process of iron ore is waste iron ore tailings
In recent years very little attention has been placed on the environmental impact of iron ore mining across the globe in terms of environmental pollution due to heavy metals compared to mines
Various mining waste types stand out including iron ore tailings [36][37] [38] kaolin waste [39 40] Bentonite is usually extracted by surface mining Bentonite mines are covered by a layer of
Environmental impacts of mining have also been evident in Brazil with some of the world s worst environmental disasters occurring in recent years For instance Vale s iron ore Flona de Carajás mine had previously received environmental licenses from the state level environmental agency in Pará but then the environmental licensing
To quantitatively evaluate the carbon emission effects of various underground mining schemes in metal mines a carbon emission calculation model specifically for underground metal mines was established The carbon emissions stemming from the mine s production process were categorized into three components carbon emissions from the production of
Iron Ore Mining There are two basic methods of mining iron ore These are • Surface mining or open pit mining • Underground or shaft mining To be competitive iron mining must be done on a very large scale Surface mining is the preferred choice although there are exceptions Small low capacity mines have rapidly disappeared
The aim of this study was to I assess the impacts of mining on soil pollution with metals in Mongolia s key coal mining towns Baganuur Nalaikh and Sharyn Gol and II review the current
