Environmental impact of mining

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.

What Is The Environmental Impact Of The Mining

For example, lead ore mining in Galena, Kansas between 1980 and 1985 triggered about 500 subsidence collapse features that led to the abandonment of the mines in the area. The entire mining site was later restored between 1994 and1995.

· Our Iron Ore dust mitigation programme is part of a broader Health and Hygiene Management Plan (HHMP) that addresses dust, water and noise management in a targeted way. The HHMP supports compliance with our regulatory requirements and the management of potential impacts on host communities and the environment.

Mining''s big environmental footprint in the Amazon

· The Amazon rainforest in South America has large quantities of copper, tin, nickel, bauxite, manganese, iron ore and gold, making it attractive to mining companies all around the world. But as the governments of the eight countries that cross the Amazon eagerly try to capitalise on this wealth, concern is growing over the deforestation caused by, amongst other things, mining.

What Is The Environmental Impact Of The Mining Industry?

The discovery and use of the "useful" metals copper and bronze at first, then iron a few millennia later had an enormous impact on human society. The impact was so pervasive that scholars traditionally divide ancient history into Stone Age, Bronze Age, and Iron Age.

Iron ore developments rejected for environmental reasons

Western Australia''s Environmental Protection Authority (EPA) has knocked back the development of two iron ore projects in the state. The environmental watchdog advised that two proposals to mine significant banded iron formations (BIF) would cause permanent and irreversible environmental impacts, leading it to recommend against their approval.

A clearer look at how iron reacts in the environment

· Because iron (II) is more soluble than iron (III), when an electron hops to an iron atom at the mineral surface, that iron (II) atom can be released into solution, and dramatically affect the chemistry and mineralogy of soils and surface waters. Iron reduction is particularly important for the mobility of contaminants in the environment.
