mine tailings environmental impact

Mine tailings are the materials left over after the process of separating the desired product from an ore. They often consist of fine particles suspended in water, which have the potential to damage the environment by releasing toxic metals, causing erosion and sinkholes, and contaminating soil and water supplies
