  • The Threat | Save the Boundary Waters

    Sulfide-ore copper mining is much more toxic than Minnesota's taconite mining. It produces giant waste piles that, when exposed to air and water, leach sulfuric acid, heavy metals and sulfates. Sulfide-ore copper mines pollute groundwater, rivers and lakes. In the history of sulfide mining, pollution has never been avoided.

  • Sulfide Mining

    Sulfide mining, unfortunately, poses several significant environmental risks. The most significant one is the threat to water quality. When sulfide ores are exposed to air and water, the result is sulfuric acid, which causes the leaching of potentially toxic heavy metals and the release of sulfates that contribute to the methylation of mercury.
