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].

Water pollution is caused by many factors including (but certainly not limited to): uncontrolled construction sites, leaking sewer lines, stormwater runoff, accidental spills and leaks, improper discharge of wastes, mining activities, foundries, animal waste, and others.
Three years ago, on 5th November 2015, the failure of a tailings dam containing millions of litres of mining waste — run by the Brazilian mining company Samarco — released a tidal wave of 50 million cubic meters of water and sediment from iron ore extraction.
Organomercury levels in fish exposed to mine drainage water can be at levels dangerous to human health. Cyanide Cyanide salts are widely used to extract gold from finely crushed ore because they combine with about 97% of the elemental gold. Typically, the NaCN solution is sprayed on heaps of ore and the liquid extract is collected.
The environmental impacts of mining a metal ore are determined partly by the ore''s percentage of metal content, or grade. The more accessible highergrade ores are usually exploited first. Mining lowergrade ores takes more money, energy, water, and other resources, and leads to more land disruption, mining waste, and pollution.
