Appendix 2: Environmental and Social Impacts of Mining

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). Disposing of such large quantities of waste poses tremendous challenges for the mining

Mines and environmental impact - SGU

Waste arising from mining is called gangue. Both surface and underground mining often require large quantities of rock to be broken away to reach the ore. Gangue is usually placed in heaps near the mine. Many Swedish mines use parts of the gangue as a resource, e.g. as aggregate for road construction or to refill mined rock chambers and open pits.

Mine Waste Transfer and Disposal Methods - Mine Tailings, Gangue

The main environmental impacts of mining waste include the loss of land following its conversion to a tailings pond or waste storage area and the introduction of acidic runoff or other contaminated sediments into the local environment.

Mining - Wikipedia

The total movement of ore and waste constitutes the mining process. Often more waste than ore is mined during the life of a mine, depending on the nature and location of the ore body. Waste removal and placement is a major cost to the mining operator, so a detailed characterization of the waste material forms an essential part of the geological ...

Tailings - Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
