Mongolia is a leading producer of coking coal, copper, iron ore and crude oil, but exports nine minerals in total. Extractive industries accounted for 20% of GDP, 18.6% of government revenue and 86.2% of total exports in 2016 according to the 2016 EITI Report.
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). Disposing of such large quantities of waste poses tremendous challenges for the mining industry and may significantly impact the environment. The impacts are often more

Aug 15, 2008· Mining and associated smelting and metal processing activities have led to perturbations in the cycling of metals in the surface environment. In this context, iron-ore mines act as important sources of major metals, mainly Fe and Mn, but also associated trace metals into the environment (Ratha and Venkataraman 1995; Wong 1981; Zabowski et al. 2001).
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.
