Metal pollution from the water leaves measurable traces in sediments, plants, and and local wildlife. Carl Jones / Flickr. Obviously, acidic mine waste (usually referred to as acid mine drainage or AMD) like the contaminated water from Parys Mountain and other sites is a problem. There are an estimated 280,000 abandoned mine sites like Parys Mountain in the UK alone.
The taconite iron ore pellets are hauled by railroad to the ports of Silver Bay, Two Harbors and the Twin Ports of Duluth, Minnesota, and Superior, Wisconsin, all on Lake Superior. The docks at Escanaba, Michigan, on Lake Michigan, also ship taconite from the Marquette iron range in Michigan, and occasionally ore from Minnesota is hauled by rail there.

Mining operations use large amounts of fresh water to process recovered ore; the resulting mine effluent is typically a stew of hazardous acidgenerating sulphides, toxic heavy metals, waste rock impoundments and water—and it is often deposited nearby in large freedraining piles where it can pollute land and water supplies for decades to come.
Iron and Water is Grant J. Merritt's memoir of his life's work on behalf of Minnesota's people and environment and also the story of a significant family in state history. Merritt's family played a key role in the struggle over natural resources in Minnesota—for the enrichment of mining pioneers, the prosperity of the state and its people, and the prospect of a secure and healthy future.

Like all other industries, mining corporations need water to make bare rock give up its valuable minerals. Mining has played an important part in the development of this Nation.
But opponents prefer to call it "sulfide mining," for the kind of ore the metals are found in and because unearthing sulfide can cause toxic water pollution.
According to data contained in Anglo American's Minas Rio licensing agreement, the mine uses 5,023 cubic metres of water per hour and its activity lowers the water table and destroys the recharge areas and aquifers, because it is in the iron ore layer that water accumulates.

The former president of a mining company that once planned to build a billion iron ore mine in northern Wisconsin is being fined for polluting an aquifer near a mine in Spain. Gogebic Taconite's president once pointed to the Spanish mine's technology as a method that could be duplicated in northern Wisconsin.
Published by the American Geosciences Institute Environmental Awareness Series. Modern mining operations actively strive to mitigate potential environmental consequences of extracting metals, and such operations are strictly regulated in the United States.
If you mean mining metals like gold, water is used to clean the dirt and separate the gold from the rocks. the water that comes out of this process is dumped back in the rivers that the came from causing more pollution.
