Environmental impact of iron ore mining Wikipedia
The environmental impact of iron ore mining, in all its phases of, This process is referred to as Acid Mine Drainage (AMD). Acid produced from AMD causes health hazards to many fish and aquatic organisms as well as land animals who drink from contaminated water sources. Many metals become mobile as water becomes more acidic and at high concentrations these metals become toxic to most

The Boom: Iron ore and Australia
Every bit of iron ore used to produce a tonne of steel gives rise to an average of about two tonnes of greenhouse gas (GHG) emissions partly due to mining and transport, but mostly due to the
Mines and environmental impact SGU
The oxidic ores predominate in Norrbotten's iron ore field, while the sulphidic ores are more prominent in, e.g. the Skellefteå field in Västerbotten. However, Sweden's largest sulphide ore mine, Aitik, is in Norrbotten. It is primarily from waste in the mining of sulphide ores that serious environmental problems can arise due to their content of iron sulphides such as pyrite and pyrrhotite

The environmental impacts of mining, although significant, are generally confined to local areas. Apart from direct physical impacts of extractive activities, contamination of air, land and water may also result. However, mining in isolation may not be the main land use that upsets ecological systems, as environmental effects are cumulative in nature and other past activities or events may
