Iron mining in the United States - Wikipedia
Iron ore was discovered on the Marquette Range in 1844, and mining started in 1848. Mining increased after the opening of the ship canal at Sault Ste. Marie provided cheap water transportation between the iron mines to the lower Great Lakes. The Lake Superior iron deposits were the largest ever discovered in the United States, and by the late 1800s, dominated American iron mining.

Mine water. Water is used in many mining processes. Large volumes of water are used in some processes, i.e. milling. In a mine process, water is a valuable resource, and is often recycled and re-used. Eventually the water is collected and released to the environment. Sometimes the water must be treated in different ways before it can be released.
