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. For a sense of scale, this Overview shows approximately one square mile of the basin.
