How Critical Minerals Mining Affects Water
Critical Minerals Mining Depletes and Contaminates Fresh Water. Most methods used to mine critical minerals today require significant amounts of water for separating minerals, cooling machinery and controlling dust. Waste from mining and processing, including residual minerals and chemicals, can also contaminate water in nearby communities.
