Leaching experiments and evidence from water samples also indicated that the legacy lithium mine does not contribute to environmentally harmful acidic runoff commonly associated with other mining operations, like coal mining. Rather, interactions between the ore and waste rock samples and water led to temporary alkaline, or basic, conditions.

Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. Problems that can be associated with mine drainage include contaminated drinking water, disrupted growth and reproduction of aquatic plants and animals, and the corroding effects of the acid on parts of infrastructures such as bridges.

Copper-sulfide mining, which is much more toxic than Minnesota's traditional form of iron mining, has never been done in the state. According to the EPA, sulfide mining is part of the most toxic industry in the country. Pollution from sulfide mining is nearly impossible to contain and can last for hundreds, even thousands of years.

To keep up with increasing metal demand and decreasing mineral content in the ore, the site capacities have been growing. In general, the lower the ore grade, the more water-intensive the extraction processes is. Higher metal demand has led to 5%-plus increases in water usage anually in the mining industry.
