Abstract. Sulfide mining (specifically copper-nickel sulfide mining) represents a significant departure from Minnesota's iron mining tradition. Sulfide mining can produce acid waste and sulfates that mobilize the release of heavy metals into the environment. These metals include known neurotoxins such as lead and mercury.

Historically, the DFL has sought a balance on mining issues in the Iron Range but Sen. Jennifer McEwen says corporate interests have kept the issue of copper-sulfide mining off legislator's tables.
Hydrogen sulfide (H2S) is a colorless, highly toxic gas that is characterized by its distinctive foul odor of rotten eggs. It is produced naturally by the breakdown of organic matter containing sulfur compounds, such as in swamps, sewers, volcanic areas, and petroleum refineries. Hydrogen sulfide is also generated by human activities, including ...

Yet, surprisingly, a new mine is now looming. In 2012, the Chilean company Antofagasta purchased old mining leases and devised a plan to build a sulfide-ore copper mine only five miles from the southern edge of the Boundary Waters. The dangerous project is advancing quickly with government support and could soon compromise this …
Sulfide Mining Differs from Iron Mining . Polymet Mining and Twin Metals Minnesota are proposing to operate coppernickel mines in hard rock formations composed of sulfide ores. These are not Minnesota's traditional iron ore and taconite mines, but a new type of toxic producing mine which would extract minerals from sulfide ores. ...
Just before Christmas, the Department of the Interior reversed an Obama administration decision and opened the door for a copper-nickel mine near the Boundary Waters Canoe Area Wilderness in the northeast Arrowhead region of Minnesota.. Northeastern Minnesota is known as the Iron Range and taconite mining is deeply tied …
Realgar, also known as "ruby sulfur" or "arsenic sulfide," is a naturally occurring mineral composed of arsenic and sulfur with the chemical formula As₄S₄. It is classified as an arsenic sulfide mineral and is typically found in association with other minerals in hydrothermal veins and volcanic deposits. Realgar is known for its striking …

Deep‐sea mining refers to the retrieval of marine mineral resources such as manganese nodules, ferromanganese crusts and seafloor massive sulfide deposits, which contain a variety of metals that ...
Sulfide mining releases of mercury and sulfur compounds to air and water increase accumulation of methyl mercury in the food chain. Loons, like humans, are at the top of the chain, and are at ...
These bills are being championed by MEP member groups, and would help prevent sulfide mining pollution from destroying some of our most valuable resources. First, on Wednesday, Minnesota Legislators introduced a bill that would enact a "prove-it-first" standard for any non-ferrous ore mine in the state. The legislation would ban any …
New rules governing sulfide mining in Wisconsin were unanimously approved Wednesday by the state Natural Resources Board. The regulations would make mining companies pay more for permits and licenses, as well as outline areas that are considered unsuitable for mining. The changes are part of proposed new permanent …

The mining of copper/nickel sulfide ores is a toxic type of mining that is risky to our environment, our workers and communities, and local economies. Mining sulfide rock releases acid and toxic metals and contaminants that pollute rivers and groundwater for hundreds of years, long after the profits are spent and the products buried in landfills.
However, the Department of Natural Resources did hire a Denver pro-mining law firm at a cost in excess of $6.4 million to represent the interests of Glencore, a foreign mining conglomerate ...
