The PolyMet project, a copper-nickel mining project (sometimes mischaracterized as sulfide mining because it involves extracting metals from sulfide ore), is undergoing a tough, but fair, environmental review and permitting process. State and federal agencies are required to evaluate and approve our plan before the project can receive permits for construction and operation. This ensures PolyMet minimizes the project impact on Minnesota’s environment and natural resources.
To protect air and water quality, PolyMet is carefully assessing energy efficiency and potential environmental impacts related to all processes, equipment, products and materials. We are using modern mining technology and operating practices, including reverse osmosis, a water collection and treatment facility, and hydrometallurgical processing.
Minnesotans will have multiple opportunities to review and discuss our plan during public meetings with regulators. We value these ongoing conversations, encourage people to get involved, and appreciate questions and feedback.
