The Michigan Iron Industry Museum in Negaunee (9 miles west of Marquette), offers photos of everyday life in mining towns and a timeline of how mine work evolved. Outside, a trail connects the museum to the 47-mile Iron Ore Heritage Trail, which passes artwork, interpretive signs and relics of the region's mining history. By Gary Thompson.

28/02/2019Mine drainage forms from a chemical reaction between water and rocks containing sulfur-bearing minerals. The resulting waters become rich in sulfuric acid and dissolved iron. As the iron settles out of the water, it can form red, orange, or yellow sediments in the bottom of streams. The acidic runoff further dissolves heavy metals such as

Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed "tailings". Typically, mill tailings range from sand to silt

Tailings Iron mine tailings (henceforth referred to as 'tailings') were obtained from a North American magnetite iron ore mine.

The water used for processing the iron-bearing material through the concentrating process also carries the silica, or tailings, to a large impoundment know as a tailings basin. At the Gribben Basin, which serves the Tilden Mine, the water is decanted and clarified so it can be returned to the watershed meeting all government clean water standards.

Michigan Tailings Tailings - the waste and byproducts from mining operations - are pumped into the Gribbens Basin next to the Empire and Tilden iron ore mines in Negaunee, Michigan, USA. Here, the materials are mixed with water to create a sloppy form of mud known as "slurry" that is pumped through magnetic separation chambers to increase the mine's total output.
