Mining | Water for all

Mining produces mainly tailings (the waste materials left after the valuable ore is separated out) and overburden (the waste materials removed to reach the ore). During the mining process, water within and around the mine is usually contaminated, so treating the mine water before it is discharged back into the environment is a major issue [2].
