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].

Final Report: Water Use and Risks in Mining
Water Use: based on sustainability reporting by many mining companies, we add detailed water data to each year of production for a given mine. Specifically, we account for water inputs and their source (groundwater, surface water, marine or third party supplied), use (raw water, worked or recycled water) and any discharges to the environment.

Water Polution Of Ore Minning
Reducing mine water requirements. If the mine could achieve a filtered tailings solids density of 90% solids by mass while rejecting 50% of the ore through pre-sorting, water consumption could reach as low as 0.06 m 3 /t of ore mined, allowing the 50,000 tpd mine to withdrawal only 3051 m 3 /day of raw water.

Its use, however, is dependent on the size and type of mine, among other factors. Just as mines differ, so too do their sources of water. Again, depending on the mine's location, it can obtain its water from various sources such as groundwater, surface water, a public water supply, or through recycling or reclaiming its own process water.
