The mining of coppernickel 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.Get Price
Northern Minnesota39s Waters and Forests Threatened by Sulfide Mining and Industrial Expansion. Located between the North Shore of Lake Superior and the Boundary Waters Canoe Area Wilderness, the Arrowhead Region is Minnesota39s most loved recreation area and a place that millions visit for rejuvenation.
WaterLegacy Advocacy Director and Counsel Paula Maccabee talks about Minnesota39s waters and communities at risk from proposed sulfide mining projects. KeepItInTheGroung Extreme Extraction.
Sulfide mining would destroy thousands of acres of habitat for loons in northeastern Minnesota, pollute lakes and streams, and create toxic pit waters, decimating loon populations throughout
Noise, dust and light pollution from 24houraday, 365dayayear mining operations would affect animal behavior and the quiet fishing experience. Mine infrastructure and additional road traffic would lead to forest fragmentation, which disrupts wildlife travel corridors and accelerates the spread of weedy invasive species, which
Although Minnesota has a long history of iron ore mining, sulfide mining for copper, nickel, and precious metals has never been attempted. Prices for some metals, including copper, reached historic highs in 2011, and some companies have sought to mine Minnesota39s lowgrade sulfide ores.
Coppernickel mining also known as 34nonferrous mining34 in northern Minnesota is not a new issue for the state. Coppernickel deposits have been known to exist in northern Minnesota since the 1800s, but it was not until 1948, when deposits were discovered near Duluth, that serious interest in mining these metals developed in the region.
On July 18, 2019, Twin Metals Minnesota suddenly announced it would use dry stacking for tailings waste at its proposed coppernickel sulfide mine adjacent to Minnesotas Boundary Waters Canoe
Sulfide mining in a waterrich environment like northern Minnesota is a highrisk gamble. We need to protect our water, our families health, our wildlife, and taxpayer resources from pollution and harm caused by sulfide mining.
Metallic sulfide mining aka hard rock mining is the practice of extracting metals such as nickel, gold and copper from a sulfiderich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created threatening to poison the nearby water
Sulfide mining record There is ample reason to be skeptical about mining companies and promoting agencies promises that sulfide mining can be done without polluting the water. One can merely search the internet for 34Acid Mine Drainage34, and find numerous examples all over the world of environmentally devastating and costly damage.
Sulfide mining is especially dangerous in northern Minnesota because of two factors The waterrich environment and the lowgrade quality of the mineral deposits. 1. WATER The clean water and seemingly endless waterways that make so many people treasure northern Minnesotas wilderness, would also amplify the effects of Acid Mine Drainage.
The mining of coppernickel 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.

MCEA is a member of the Mining Truth coalition, which includes Friends of the Boundary Waters Wilderness and Conservation Minnesota. Sulfide mining in Minnesota would affect many of our treasured places, including Lake Superior and the Boundary Waters. Its too important of an issue to be uninformed.
On March 7, Governor Mark Dayton released a letter he sent to Twin Metals Minnesota, owned by international mining company Antofagasta, about the need to protect the Boundary Waters. The letter outlines his grave concerns about Twin Metals proposed massive sulfideore mining operation in the Boundary Waters Wilderness watershed.
But environmentalists are not happy. The term sulfide mining is a lightning rod. On a recent spring day, Minnesota39s mining experts met in the Duluth convention center.
The process of mining copper and nickel are so different from the process of mining iron ore that we, as residents of this area, and anyone who values the BWCA and their experiences here, must look carefully at the downside of sulfide mining and the likelihood of acid mine drainage into the BWCA.
Sulfide Mining in Northeastern Minnesota Far and away, Metallic Sulfide Mining represents the greatest current threat to the BWCAW and its environs. The extraction of heavy metals gold, copper, palladium, nickel and others from sulfide bearing o re has the potential to contaminate waters flowing into the Wilderness.
Sulfide Mining Fact Sheet Sulfide Mining and Minnesotas Wild Rice Sulfate Standard Impact of Mining on Sulfate Levels in Minnesota The type of pollution that comes from sulfide mining is particularly dangerous to wild rice. Our state grain is extremely sensitive and more vulnerable to pollution and habitat loss than other species.
