ESG Industry Report Card: Metals And Mining

In all its forms, mining has the potential to release toxic elements to the air, water, or soil. Open-pit and underground mining involve the crushing and treatment of large amounts of ore, which may alter ecosystems if containment isn't proper. Other forms of mining, such as heap leaching, use toxic fluids (i.e. cyanide, sulfuric acid)
