Environmental Impacts of Mining in the Keweenaw

The majority of copper mined here was native copper, 99.99% pure copper. Fortunately, this means that the waste products of mining here were more benign than in other parts of the world—but there still are long lasting environmental impacts. The main byproducts of copper mining in the Keweenaw were waste rock piles from the mines, tailings

Is Recycling Copper Good for the Environment?

Mining of copper produces dust and waste gases like sulfur dioxide, which contributes to air pollution. While miners minimize this pollution by trapping sulfur dioxide gas and using it to make sulfuric acid, the process of recycling copper rarely contributes to gas emissions that can pollute the environment.
