In some countries, mining is responsible for significant amounts of water use, as well as water waste. Environmentally, potential negative effects of mining can include air, land/soil and water pollution of different kinds. Mining produces potentially hazardous/toxic tailing waste, and can leach toxic chemicals, heavy metals and air …
