The Save Lake Superior Association, a grassroots citizen group, proved instrumental in holding the Reserve Mining Co. to account for dumping iron mining waste into Lake Superior from 1955 into the 1970s. The pollution introduced asbestos …
Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. The resulting chemicals in the water are sulfuric acid and dissolved iron. Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage.
Press Release: December 2, 2020.

The six iron ore processing plants in northeastern Minnesota would be required to cut their emissions by 57% by the end of 2026. They're the largest source of mercury pollution in Minnesota, accounting for about half its emissions. The rule also applies to two mining operations in Michigan's Upper Peninsula.
Mining activities can have significant effects on our air, water, and soil quality. These activities release pollutants and toxic chemicals into the environment, which can be harmful to both humans and wildlife. Moreover, mining can lead to habitat destruction and biodiversity loss, threatening our unique Aussie ecosystems.
Bibliography Note at the Outset: For the sake of keeping these posts readable, especially since I don't have a footnote function here, I am not going to laboriously cite everything at each point of reference, but instead I am going to include a bibliography up-front for the entire series.For the beginner looking to get a basic handle on the pre-modern iron-production …
Direct and indirect greenhouse gas emissions from mining for green technologies need to be accurately and transparently accounted for, as highlighted by a case study of …
The environmental impacts of mining are the subject of increased community scrutiny. In response to crucial environmental and community concerns we have invested over two decades of R&D developing science and technologies that help minimise environmental impacts prior to, during and post-mining, to support a sustainable future for the industry and society.
Furthermore, all active and abandoned mine waste facilities represent a significant risk for both companies and local communities – as the breaching of the Brumadinho dam disaster, which killed 270 people at the Vale Córrego do Feijão iron ore mine in Brazil, demonstrated in the extreme.
Land use change driven by mining is a major environmental concern, affecting ecology and local populations via habitat destruction, water use, and pollution. The provenance of the iron ore used in steel products is difficult to identify for …
In addition, we also include iron (Fe) ... is vital to address local to global health and wellbeing challenges arising from environmental pollution, such as from mining- and mine-related metalliferous dusts. Research at the …
Mineral nodules on the seafloor in the Clarion-Clipperton Zone, a key area of interest for deep-sea mining. Photo by ROV KIEL 6000/GEOMAR. In the case of polymetallic nodules — which are currently the primary focus for deep-sea mining — mining vehicles would collect mineral deposits from the surface of the seabed, not unlike a tractor plowing a field, …
As mining operations increased, so did pollution. Acid mine water seeping into the Sacramento River, sizable fish kills, and sediment deposits in the Spring Creek Arm of Keswick Reservoir have all plagued the area. To compound the issue, the city of Redding receives its drinking water from the Sacramento River, downstream from the Iron Mountain ...
PM 2.5 is derived from common sources of atmospheric pollution, such as automotive vehicles, mining operations, biomass burning, and industrial emissions (Nor et al., 2021).PM is harmful to health because it contains chemical compounds, especially PM 2.5, with a high range and strong absorption capacity (Ding et al., 2021).Additionally, PM 2.5 inhalation …
The effects of mining for the clean energy transition. Global climate change is understood to be the most pressing environmental issue facing humanity today. Mitigating climate change requires reducing carbon emissions …
The most-traded May iron ore contract on China's Dalian Commodity Exchange touched $163.11 a tonne and has fallen 6% this week. China's Ministry of Ecology and Environment has urged the ...
Mining, whether for fossil fuels or metals used in clean energy technologies, has serious environmental impacts, and it's hard to make apples-to-apples comparisons—except …
Mining can directly and indirectly affect social and environmental systems in a range of positive and negative ways, and may result in societal benefits, but may also cause conflicts, not least in relation to land use. Mining always affects the environment, whilst remediation and mitigation efforts may effectively ameliorate some negative environmental …
Automated air quality monitoring systems can measure air quality, low and high levels of criteria pollutants, as well as other gases and toxins, and helps ensure ambient air quality complies with local environmental regulations. The MAQS Mine air quality station is an affordable underground mine ventilation monitoring station.
On 5 November 2015, a waste dam at an iron-ore mine in southeastern Brazil collapsed, unleashing a tide of slurry that killed 19 people, displaced hundreds more and …
Heavy metal pollution has attracted more attention due to the toxicity and migration characteristics, which has close relationship with soil environment and food safety.
