Environmental Problems Ore Mining

An important step in curbing the pollution created by mining and ore processing is to work with mines and governments to improve mining equipment and environmental regulation. Many pollution problems occur due to a lack of set environmental and health standards, or, when laws do exist, weak enforcement and compliance procedures.
